12 MIND-BOGGLING SPACE FACTS
Aug 8, 2026
1. The ISS is only 200-ish miles away from the Earth's surface. You probably drive more than that every week.

2. Pluto has cryogenic volcanic activity - literally, ice volcanoes.

3. Olympus Mons, on Mars, is the biggest mountain in the Solar System.
It's huge, but it's so spread out, it would be an easy climb. You could just walk right up it, and that would be relatively easy because of Mars' weak surface gravity.

4. There's a type of neutron star called a "magnetar" which has a magnetic field that's so powerful that being within 1,000 miles of one would warp all the atoms in your body.
Even from a distance of 100,000 miles away, it would be able to wipe out the data of every credit card in your wallet.

5. Not only are there rogue planets floating through space completely alone and not orbiting any stars, but it's possible that these pitch-black, lonely planets support life.

6. The Moon is about 1/400th the diameter of the Sun, but also about 1/400th the distance from Earth.
This results in the Moon and the Sun appearing as about the same size in the sky, a coincidence not shared by any other known sun-planet-moon combination.

7. There's an asteroid called "TB 145" that really is the shape of a human skull and came closest to the Earth in 2015 on Halloween.

8. All the planets in the Solar System can fit between the Earth and the Moon with about 5,000 miles to spare.

9. The Milky Way, Andromeda, and all the nearby galaxies are being pulled into something that we can't see that is tens of thousands of times more massive than our galaxy. It is called "The Great Attractor."

10. This picture of a photogenic pair of interacting galaxies taken by the Hubble Space Telescope is called "Rose of Galaxies."

11. A lot of people already know that if the Sun suddenly disappeared, we'd still get its light for about eight minutes, but an additional fun fact is we'd also be subject to its gravity for those same eight minutes.

12. There is so much space debris orbiting Earth that in the future it may become dangerous just to leave Earth, and we could get trapped in our own garbage. This conundrum is called the "Kessler Syndrome."
