With new space discoveries happening weekly, it’s no surprise we wanted to write these 100 random & interesting facts about space!
Space facts are
interesting to learn!
Equally time goes by, technological advancements have seen the states learn more facts most space in the by century than in all time before that.
Nosotros’ve literally searched the universe for the most astonishing infinite facts, including facts about the planets in our solar organization, moons, the Milky Way, and across! We’re pretty sure #100 will make you smile!
Before y’all begin your journey through fourth dimension & space, bank check out our video below with our 5 favorite space facts from this list!
Without further ado, let’s launch right into these 100 crazy facts virtually space!
Mercury & Venus are the only 2 planets in our solar system that take no moons.
In total, there are 176 confirmed moons that orbit the planets in our solar system, with some of them being bigger than Mercury itself!
If a star passes too close to a black hole, information technology can be torn apart.
For 20 years, a team of astronomers observed a star at the middle of our galaxy orbiting a blackness hole.
The star has now got close enough to the black hole for “gravitational redshift” to occur which is where the star’s low-cal loses energy every bit the black pigsty’southward gravity intensified.
The hottest planet in our solar system is Venus.
About people think that this would be Mercury, as it is the closest planet to the sun.
However, Venus has a lot of gasses in its atmosphere which creates a “Greenhouse Upshot” that causes a constant temperature of 864° Fahrenheit (462° Celsius) everywhere on the institute’s surface.
Our solar system is 4.57 billion years sometime.
Well, requite or take 30 1000000 years(ish). Accurately speaking, it is 4.571 billion years old.
Scientists guess that in nigh 5 billion years, our Sun will expand becoming a Ruby-red Giant.
In nigh 7.5 billion years its expanding surface volition swallow up and engulf the Globe.
Enceladus, one of Saturn’s smaller moons, reflects ninety% of the Sun’s lite.
Considering Enceladus’ icy surface reflects sunlight rather than arresting information technology, temperatures attain every bit depression as -394° Fahrenheit (-201° Celsius).
The highest mountain discovered is the Olympus Mons, which is located on Mars.
Its height is 16 miles (25 km) high, making it almost 3 times higher than Mountain Everest.
And not only is it alpine, simply information technology’south too 374,015 ft² (114,000 m²) wide – that’s an expanse the size of Arizona!
The Whirlpool Galaxy (M51) was the first celestial object identified as being spiral.
The 1000, spiraling arms of the Whirlpool Galaxy are fabricated up of long lanes of stars and gas, sprinkled with lots of space grit.
These arms deed equally star formation factories, compressing hydrogen gas and creating clusters of new stars.
A light-yr is the distance covered by light in a single year.
Low-cal moves at the velocity of most 186,411 miles (300,000 km) a second.
And then 1 light-twelvemonth equates to roughly 5,903,026,326,255 miles!
The Galaxy galaxy is 105,700 calorie-free-years wide.
It would have a modernistic spacecraft 450,000,000 years to travel to the center of our milky way!
You lot can read more unbelievable infinite facts with this listing of Milky Way facts!
The Sunday weighs about 330,000 times more Earth.
It is about 109 times the diameter of World and is so big the Earth could fit inside the sunday well-nigh i,300,000 times over!
In fact, the sun is so gigantic that it contains 99.85% of all mass in our solar system.
Footprints left on the Moon won’t disappear as in that location is no wind.
But wait a minute… if there’south no current of air to blow them away and then why is the flag blowing? Well, it actually wasn’t blowing.
That rippling yous see is because of a stubborn telescopic horizontal rod that the astronauts were struggling to remove from the flag’s upper hem.
Yet unsure whether nosotros’ve walked on the Moon? Here are 5 common Moon landing myths debunked.
Because of lower gravity, a person who weighs 220 lbs on Earth would weigh 84 lbs on Mars.
When sending droids to the surface of Mars, this is something scientists programme for, existence able to load the droid upwards with more equipment and build information technology from more than robust materials.
There are 79 known moons orbiting Jupiter.
Jupiter is the planet in our solar system with the well-nigh moons, and information technology also has the largest moon in our solar organization.
That moon is called Ganymede and is 33,279 miles (5,262 km) in diameter – that’due south bigger than Mercury and it is visible with just a pair of binoculars!
The Martian mean solar day is 24 hours 39 minutes and 35 seconds long.
So you’d therefore presume in that location are less days in a year on Mars than Earth, correct? Wrong!
Because Mars orbits the lord’s day slower than the Earth, in that location are actually 687 Martian days in a Martian year!
NASA’s Crater Observation and Sensing Satellite (LCROSS) found evidence of water on the Earth’s Moon.
Whilst h2o cannot exist on the Moon’s surface under its electric current atmospheric condition, scientists believe h2o ice could survive inside the common cold, permanently adumbral crates at the Moon’s ii poles.
The Sun makes a full rotation once every 25 – 35 days.
So for us on Globe, one full rotation equals one full solar day. Yet, our gargantuan dominicus takes 25 – 35 Globe days to brand one full rotation!
Want to learn more than space facts? Check out these twoscore fiery facts nearly the Lord’s day!
Globe is the merely planet not named after a God.
Nobody knows how the Earth got its name; all we know is that it is derived from an amalgamation of both the Former English and Old Germanic words for “ground”.
Due to the Dominicus and Moon’s gravitational pull, we take tides.
This is considering the Moon’s tidal forcefulness causes the Earth – and the water on information technology – to bulge out on the side closest to the Moon.
These bulges are what cause the earth’s loftier tides.
Pluto is smaller than the United States.
If y’all were to walk effectually the equator of Pluto it would be the same altitude equally walking from London to Denver (well, give or take 56 miles).
According to mathematics, white holes are possible, although every bit of yet we take found none.
A white hole is a hypothetical region of space-time which can’t be entered from the outside, although matter and calorie-free tin escape from within.
Basically, information technology’southward the opposite of a blackness pigsty.
There are more volcanoes on Venus than whatever other planet in our solar system.
In that location are more 1,600 major volcanoes across the surface of Venus, including a 5 mile (8 km) loftier volcano called Maat Mons.
However, none of these volcanoes are known to be erupting at nowadays and well-nigh are probably long extinct.
Uranus’ blue glow is due to the gases in its atmosphere.
Uranus’ atmosphere is made up of hydrogen, helium and methane.
The marsh gas in Uranus’ upper atmosphere filters out all the blood-red low-cal from the Lord’s day but reflects the Sun’southward blueish light dorsum into space, giving it its blue appearance.
Enjoying our space facts? If you’re interested in learning more, we take more interesting facts about Uranus.
In our solar system that are 4 planets known equally gas giants: Jupiter, Saturn, Uranus & Neptune.
A gas giant is a large planet that is made upwards mostly gases similar hydrogen and helium, and has only a relatively small rocky core.
Uranus has 27 moons that accept been discovered so far.
Information technology has v large moons, and 22 small moons. Titania is the largest of Uranus’ moons and is the eighth largest moon in our solar system with an average diameter of 980.5 miles (1,578 kilometers).
Because of its unique tilt, a season on Uranus is equivalent to 21 Earth years.
Also the 97.77 degrees tilt on Uranus’ axis ways that a twenty-four hours there only final 17 hours, 14 minutes and 24 seconds.
Neptune’s moon, Triton, orbits the planet backwards.
Triton is the only large moon of any of the planets that does this.
This is known as a retrograde orbit and astronomers are unsure as to why Triton orbits Neptune this style.
Triton is gradually getting closer to the planet it orbits.
Scientists believe that when Triton eventually gets likewise close to Neptune, it volition be torn apart by the planet’south gravity and could potentially create another ring around Neptune – giving it more rings than Saturn.
There are more stars in space than there are grains of sand in the world.
In that location are x times more stars in the night sky than grains of sand on the World, with 70 sextillion stars being visible from Earth through a telescope.
To put that in numbers, 70 sextillion is this: 70,000,000,000,000,000,000,000.
Neptune takes nearly 165 Earth years to make one orbit of the Sun.
That’s equivalent to 60,190 Earth days to orbit the sunday in one case! Neptune has a very ho-hum orbital speed of iii.37 miles per 2d (5.43 km/s).
This means that since it was discovered in 1846, it has but completed only one orbit!
Yous may also like these interesting facts about Neptune that are outta this world!
Pluto’s largest moon, Charon, is one-half the size of Pluto.
The same surfaces of Charon and Pluto always face each other, which is known as mutual tidal locking.
The International Space Station is the largest manned object ever sent into space.
At 119 yards (109 meters) long, the International Space Station (ISS) sits roughly 250 miles (400 km) above the Globe and is the third-brightest object in the night heaven.
A day on Pluto is lasts for 153.6 hours long.
This equates to 6 days nine hours and 36 minutes. A day on Pluto lasts so long because of its dull rotation rate.
Bank check out these other interesting space facts about the Dwarf Planet, Pluto.
Saturn is the second largest planet in our solar system.
It has a radius of 36,184 miles (58,232 km) – nine times that of Earth.
Even so, due to its depression density it only has a weight roughly one-eighth of Globe.
Whatsoever free-moving liquid in outer space volition grade itself into a sphere.
This is because of something chosen surface tension, which is an imbalance of intermolecular attractive forces.
This can also occur in low Earth orbit.
Mercury, Venus, Earth & Mars are known as the “Inner Planets”.
They are named the Inner Planets because they orbit closest to the Sun.
An inner planet is classified as a planet located within the asteroid belt.
We know more about Mars and our Moon than nosotros exercise most our oceans.
We have fully mapped 100% of the surface of Mars and Globe’due south Moon, whereas nosotros have only been able to map roughly 5% of the ocean floor.
The Black Arrow is the only British satellite to be launched using a British rocket.
Black Arrow was adult during the 1960’s and was used for four launches between 1969 and 1971.
In 2019 it was retrieved from its crash landing site in the Australian outback and put on a display Penicuik, Scotland.
Only 5% of the universe is visible from Earth.
68% of the universe is nighttime free energy and 27% is dark matter. Both of these are invisible, fifty-fifty with a telescope, which means we are only able to see 5% of the universe.
Light travels from the Sunday to the Earth in less than x minutes.
The Photons emitted from the Sunday’southward surface travel beyond the vacuum of space at the speed of light to reach our optics in but viii minutes and 20 seconds.
At any given moment, at that place are at least 2,000 thunderstorms happening on Globe.
Worldwide, in that location are an estimated 16 million thunderstorms each year.
Roughly 100,000 of these thunderstorms happen in the U.Southward. lonely.
You lot tin can read more than strange facts about thunder and lightning here.
The Earth’south rotation is slowing slightly every bit time goes on.
This means that days were shorter in the by. This is considering of the tidal effects the Moon has on the World’southward rotation.
If you lot were driving at 75 miles per hour, it would have 258 days to bulldoze effectually Saturn’s rings.
Saturn’s rings are roughly 175,000 miles long, although they are only about 3,200 feet thick.
Yous can find out more interesting facts about Saturn’s rings here!
Outer Infinite is only 62 miles abroad.
Although there is no official solid boundary for where space begins, the Kármán line sits at 62 miles in a higher place sea-level and is conventionally used as the offset of outer space in space treaties or for aerospace records keeping.
The International Space Station circles Earth every 92 minutes.
The speed of the ISS every bit information technology orbits Earth is roughly 17,150 miles per hour – that equates to five miles a 2nd!
Stars twinkle considering of the way low-cal is disrupted as it passes through Earth’s atmosphere.
Starlight is affected by the winds in our atmosphere equally it enters, as well equally being affected by dissimilar areas and temperatures.
This causes the light from each star to twinkle equally we look at them.
We e’er encounter the same side of the Moon, no matter where we stand on Earth.
This is considering the Moon rotates on its centrality at the aforementioned rate that it rotates the Globe. It’s known as synchronous rotation or tidal locking.
In that location are three main types of galaxies: elliptical, spiral & irregular.
The Milky way milky way, the ane that our solar organisation resides in, is classified as a spiral galaxy.
There are approximately 100 thousand million stars in the Milky way.
Out of all the known galaxies, the Milky Way is the i that contains the nearly stars.

Buzz Aldrin’southward birth proper noun was Edwin Eugene Aldrin Jr.
He got the nickname “Buzz” from his sister’southward mispronunciation of the word “brother”, which became “buzzer”.
In 1988, he legally changed his first name to “Buzz”.
On Venus, information technology snows metal and rains sulfuric acid.
This is because Venus is a scorching planet choked with sulfuric acid, which causes the planet’s metals to become gas and and so liquid in the atmosphere, before raining down to the ground after the freezing temperatures turn information technology into a solid.
The Mariner x was the outset spacecraft that visited Mercury in 1974.
It was launched at NASA’s Kennedy Space Heart in 1973 and flew by Venus three months after. It so crossed into Mercury’due south orbit managing to photograph 45% of Mercury’due south surface.
The second spacecraft to visit Mercury was the “Messenger”, which completed mapping of 100% of Mercury’s surface in 2013.
Infinite is completely silent.
This is because there is no air in space, and air is needed to behave the sound vibrations.

This is the Velcro patch’s ane and only purpose.
The ISS is visible to more than than 90% of the Earth’s population.
When you see the International Space Station (ISS) in the nighttime sky it appears equally a fast-moving star crossing from horizon to horizon.
Saturn is the only planet that could float in water.
Although Saturn is the second largest planet in our solar organization, it is also the lightest planet.
Saturn could float in water because it is more often than not made of gas – although the real fact here is that you would need a giant bath tub!
Asteroids are the byproducts of formations in the solar organisation, more than 4 billion years agone.
The nativity of Jupiter in our solar system prevented whatever planetary bodies forming betwixt Mars and Jupiter, causing the small objects that were there to collide with each other and fragment into asteroids.
Astronauts tin can’t burp in space.
This is because the lack of gravity in infinite ways the air in astronaut’s stomach doesn’t dissever and rise up from ingested food.
Uranus was originally called “George’s Star”.
This name was in honor of discoverer William Hershel’s new patron, Male monarch George Iii.
The name “Uranus” was proposed in 1782, one year afterwards its discovery, merely wasn’t officially used until 1850.
Y’all may like these facts about when the planets in our solar system were discovered.
A sunset on Mars is blue.
Mars has less than 1% of the Earth’s temper.
So the sunsets on Mars announced as blue due to the way the blue light from the Sunday is captured within the temper of Mars.
The Globe weighs about 81 times more than than the Moon.
The Moon’south gravity, much like other planets, differs depending on where you are on its surface.
The offset living mammal to become into space was a dog named “Laika” from Russia.
Laika was a stray mongrel from the streets of Moscow and was launched into space on the Soviet spacecraft Sputnik 2 on Nov iii, 1957.
Sadly, Laika died 5-7 hours into the flight due to overheating and stress. Poor doggo.
The word “astronaut” means “star sailor” in its origins.
It is derived from the Greek words “astron”, meaning “star”, and “nautes”, which means “crewman”.
So, the discussion astronaut literally means “star sailor”.
“NASA” stands for National Aeronautics and Infinite Administration.
It is an contained agency of the Usa Federal Government and was established in 1958.

Mercury has no atmosphere, which means there is no wind or weather.
Instead of an atmosphere, Mercury possesses a sparse exosphere made up of atoms blasted off the surface past the solar wind and striking meteoroids.
In Prc, the Milky Way is known as the “Silvery River”.
In Japan and Korea “Silver River” ways galaxies in full general, not just the Milky way.
Red Dwarf stars that are low in mass tin can burn continually for upwards to 10 trillion years!
A Red Dwarf is a small and cool star in a subsequently phase of its life and has a surface temperature of less than seven,200k degrees Fahrenheit.
Scientists once believed that the aforementioned side of Mercury always faced the Sun.
However, in 1965 astronomers discovered that the planet rotates three times during every 2 orbits it makes.
Jupiter’s Reddish Spot is shrinking.
Jupiter’south red spot is a huge swirling hurricane-like storm that used to be three times the size of Earth! However, the storm is shrinking over time, merely even as it shrinks it gets taller.
Scientists are still stumped every bit to what’south causing this although they believe it may be to do with jet streams on Jupiter changing location or direction.
A big per centum of asteroids are pulled in by Jupiter’s gravity.
For this reason, Jupiter is known as the dumping grounds for our solar system.
Many of the asteroids that are potentially harmful to Earth, the long period comets, tend to be sucked into Jupiter’s gravity field.
A 24-hour interval on Mercury is equivalent to 58 Earth days.
This is considering Mercury rotates on its axis very slowly compared to Earth.
Every bit space has no gravity, pens won’t work.
Normal pens work past gravity pulling the ink towards the pen’s nib (the writing function) – as you hold the pen in your hand writing function facing downwards.
As there’due south no gravity in space, the ink doesn’t get pulled to the nib.
However, special pens have been made that work in zero gravity.
On average it takes the light just 1.3 seconds to travel from the Moon to World.
The altitude betwixt the Globe and the Moon is simply 238,855 miles (384,400 kilometers).

After 164BC in that location was a continuous recording of the comet each time information technology was visible.
In 2006, the International Astronomical Wedlock reclassified Pluto as a dwarf planet.
This is because Pluto does non gravitationally dominate the neighborhood around its orbit.
There are v Dwarf Planets recognized in our Solar Organisation.
The Dwarf Planets are Ceres, Makemake, Haumea, Eris and Pluto.
The dwarf planet Ceres is also the largest asteroid in our solar system, and resides in the asteroid chugalug, making it the just dwarf planet to not inhabit the outer solar system.
Mars is the virtually likely planet in our solar system to exist hospitable to life.
In 1986, NASA found what they believe may be fossils of microscopic living organisms in a rock recovered from the surface of Mars.
Halley’south Comet will pass over Earth once again on July 26, 2061.
This space fact is one for kids to look frontward to!
The famous comet was terminal seen on February 9, 1986, and just orbits the Earth once every 75 – 76 years.
There is a planet half the radius of the World with a surface made up of diamonds.
55 Cancri due east has a mass eight times that of Earth’s despite having one-half the radius, and may very well have a surface fabricated up of graphite and diamonds.
