25 Useless Facts About Space That Are Still Cool To Know

Space is awesome, even astonishing, and there are many reasons to be excited about the discoveries which have already been made and continue to be made in the great beyond. But, this list isn’t about the wonders of space or how cool the universe around us is. Rather, it’s about a host of facts which are completely useless, random, or mostly irrelevant. (Though, if you’re an amateur astronomer, you’re likely to find all of these to be cool facts.) Did you know South Korea spent a million dollars just to make a stench-free plate of kimchi? How about how many human remains have been launched out among the stars? Or that a vapor cloud with water 140 trillion times more massive than all the water in our oceans combined exists? From the cost of a NASA space suit to a planet which is a massive engagement ring, there are plenty of facts we’ve learned about space that haven’t really furthered our discovery or which are just plain pointless. Enjoy the worthlessness in this list of 25 Useless Facts About Space That Are Still Cool To Know.

An ungrateful prize committee

One of the most influential cosmologists in history, Edwin Hubble has a crater, planetarium, asteroid, and even the famous Hubble Space Telescope named after him. Despite his contributions to the field of astronomy, Hubble never received the Nobel Prize because the Nobel Committee did not have a category for astronomy and refused to include astronomy with physics at the time.

23

A suit way pricier than Versace

A useless space fact for us but useful for the finance team, the cost of an entire NASA space suit is 12 million dollars.

22

Neil Armstrong wasn't born to be an actor

Actors have plenty of lines to remember and only rarely mess one up. Neil Armstrong had one line to say when he became the first man on the moon and he botched it. Armstrong was supposed to say “That’s one small step for a man, one giant leap for mankind.” He left out the “a”, making the sentence redundant.

21

Betelgeuse! Betelgeuse! Betel…

The popularly-cited star (and a name you shouldn’t try to say three times), Betelgeuse is a red star that is so massive its diameter is larger than the diameter of Earth’s entire orbit around our best-known star, the sun.

How likely we are to get hit with space debris

space debris STS-41-C-LDEF-deploy-smallSource: European Space Agency, Image: Wikipedia

Our annual risk of getting seriously injured by a piece of space debris entering the atmosphere and landing on Earth is 1 in 100 billion. If you’re worried about 1,000 ways you could die, this might not be so useless a space fact after all.

19

Massive celestial bodies

SolarSystem_OrdersOfMagnitude_Sun-Jupiter-Earth-MoonSource: Space Facts & The Planets, Image: Wikimedia

Jupiter’s mass is 2.5 times greater than that of all the other solar system planets combined. Despite this useless fact, an even more useless one may be that the sun makes up 99.86% of the mass in the entire solar system.

18

Water can miraculously float around space

Europa-WaterPlume-ArtistConceptSource: The Planets, Image: Wikipedia

In a galaxy far, far away – about 10 billion light years to be more precise – a massive vapor cloud is home to water with a mass 140 trillion times greater than the mass of all the water in Earth’s oceans.

17

Volume of the moon in comparison to the Earth

Compared to Earth bodies, the volume of the moon would roughly equal the volume of the Pacific Ocean. Maybe an interesting fact, definitely a useless fact.

16

A 10 decillion-carat diamond

Wide-field_view_of_the_parent_star_of_the_famous_exoplanet_Tau_Boötis_bSource: Chicago Tribune, Image: Wikipedia

Nicknamed Lucy, star BPM 37093 is a white dwarf star about 20 light years from Earth. (That’s pretty close, relatively speaking.) Kim Kardashian may want to consider visiting the star since it is a massive diamond the size of our moon. If assessed by jewelers, the diamond would be 10 decillion carats or, numerically, 10,000,000,000,000,000,000,000,000,000,000,000 carats.

15

The Sombrero Galaxy

There’s a galaxy about 28 million light years from earth that looks like – you guessed it – a Mexican sombrero. With a dark sky and strong binoculars, the galaxy can be seen from Earth.

14

Where Mars gets its name

Mars’ surface is rich in iron, giving it a reddish color. This composition has led to cultures as far back as the Egyptians naming it after the color. The Egyptians named it Her Desher (“the red one”), the Chinese named it “fire star”, and the Romans named it Mars, after their god of war (equivalent to Ares in Greek mythology).

13

Astronauts' special pre-liftoff diets

NASA_astronauts_toasting_with__vodka__in_space_-_AST-03-175Source: Freeman Institute, Image: Wikipedia

Astronauts are on strict dietary regiments before blasting off, one of which includes eliminating beans from their diets. Apparently scientists haven’t yet found a way for space suits to deal with passing gas.

12

A year on Venus is shorter than a day on Venus

Venus orbits the sun faster than our own Blue Planet, but it spins remarkably slower. It takes the planet 225 Earth days to make one full rotation around the sun but 243 Earth days to make a complete turn on its axis. Thus, a year on Venus is shorter than a day.

11

A close call for Apollo 11

Apollo 11, the spacecraft which transported Neil Armstrong, Buzz Aldrin, and Michael Collins to the moon landed on the lunar surface with only 20 seconds of fuel remaining.

A smaller star with a larger mass

The densest and tiniest stars which have so far been found, neutron stars can have a mass many times that of our sun while being only 12.4 miles (20 km) across.

How Jovian and jovial are related but aren't

Jupiter_familySource: Chicago Tribune, Image: Wikimedia

Jupiter is a Jovian planet, meaning it’s made primarily of gases rather than of solid matter. On the other hand, jovial (a word meaning cheerful) comes from Jove, an alternative name for the god Jupiter, so Jovian and jovial are definitionally unrelated.

8

What would happen if the Earth stopped spinning

Earth_precessionSource: Universe Today, Image: Wikipedia

Though gravity keeps us with our feet on the planet’s surface, if standing on the equator, we’re each shooting through space at 1,040 miles per hour (1,674 kmh). A transoceanic Boeing 777 can only reach top speeds of 590 miles per hour. If the Earth magically stopped spinning, we wouldn’t all be hurtled into space, though, as Earth’s escape velocity is 25,020 miles per hour (40,000 kmh).

7

Our galaxy is about to crash into another one

Andromeda_Collides_Milky_WaySource: The Planets, Image: Wikipedia

Well, “about to crash” could be relative. The Andromeda Galaxy is on a collision course for our own at a speed of 68 miles per second (110 km/s). Despite the speed, this space fact is pretty irrelevant as it won’t happen for another four billion years.

6

The most expensive kimchi ever made

Korean_astronauts-Space_station_trainingSource: Chicago Tribune, Image: Wikipedia

One of South Korea’s best-known culinary exports, kimchi was brought aboard the International Space Station in 2008 by astronaut Yi So-yeon. Before he blasted off with the pickled cabbage, the South Korean government spent over a million dollars to ensure the smell wouldn’t be too acrid for the other astronauts.

5

Metal can instantly fuse in space

A useless space fact for anyone who’s not a space welder, if two particles or pieces of the same kind of metal (e.g. aluminum, copper, etc.) come into contact while in space, they will immediately fuse together. Referred to as cold welding, the objects will bond because their atoms have nothing in between (such as air or water) to hold them apart.

4

The lasting footprints on the moon

Any footprint which astronauts who have landed on the moon left in the lunar surface will remain there for millions of years. Since the moon has no atmosphere, neither wind nor water can wipe the prints off.

3

The sun also orbits another body

Though we generally only think of the planets orbiting the sun, our most famous star is also in orbit – around the center of the Milky Way Galaxy.

2

It's impossible to know how many stars exist

Milky way galaxySource: The Planets, Image: Pixabay

Astronomers are able to estimate, with a huge margin of error, how many stars are in our own galaxy, the Milky Way. This number stands between 200-400 billion stars. We’re constantly discovering new galaxies and, with billions of galaxies expected to exist, it’s impossible to estimate the number of stars in the universe.

Human ashes in space

Over 100 humans have had their ashes launched into space, including Gene Roddenberry (Star Trek creator) and Timothy Leary (an American psychologist and advocate for psychedelic drugs). Clyde Tombaugh was the first person to discover Pluto and his ashes will have been the first to leave the solar system after passing by Pluto in 2015.
