1. Astronauts grow taller in space because of the lack of gravity, which expands the disks in their spines and makes them taller.
2. There are five officially recognized dwarf planets in our solar system: Dysnomia, Nix, Charon, Hydra, Namaka, Hi’ iaka .
3. There are 500 extrasolar planets have been found in space.
4. The temperature in space is about -270.45 degrees C.
5. The planet Saturn has 82 known moons, and more are being found.
6. Mercury’s temperature varies from -280 degrees F on its night side to 800 degrees F during the day.
7. Uranus’ blue glow is due to the gases in its atmos-phere.
8. There is a planet called “55 Cancri e”, a Super-Earth” believed to be covered in graphite and dia-monds.
9. There is dark matter in space.
10. Extrasolar planets are located outside the solar system. They come in different sizes.
11. Neuron stars are the densest and smallest stars in the universe. They can rotate up to 60 times per second after they are born from a super-nova star explosion.
12. The solar system’s boundary ends in a spheri-cal cloud known as the Oort cloud.
13. When the moon is half-full, it is only 10% as bright as the full moon.
14. A dwarf planet is a planet-like object that does not dominate the neighborhood of its orbit.
15. There are more stars in the universe than grains of sand in all the earth.
16. Most galaxies have a black hole.
17. Exoplanets are planets that orbit other stars.
18. If you scream in space, no one can hear you.
19. Jupiter, Saturn, Uranus, and Neptune have all been observed having light shows known as auro-ras.
20. Uranus is often called “the sideways planet,” and it orbits the Sun on its side. It is tilted about 98 degrees.
21. No sound exists in space because molecules are too far apart to transmit sound.
22. All planets in the solar system have been visit-ed by uncrewed spacecraft.
23. Mars has a canyon system that is larger than the Grand Canyon.
24. Saturn’s moon, Enceladus, is the most reflec-tive body in the solar system.
25. The Sun is 400 times larger than the Moon and 400 times as far away, making both objects appear the same size in our sky.
26. Mercury is the closest planet to the sun.
27. The Sun can fit one million Earths inside it.
28. Space does not begin at a specific altitude above Earth.
29. Massive stars end their lives through superno-va explosions.
30. Over 100 artificial satellites are launched into space each year.
31. Spacecraft have visited all the known planets in our solar system.
32. If you drove a car to the nearest star at 70 mph, it would take more than 356 billion years.
33. Olympus Mons is the largest known volcano in space.
34. The reason space is so dark is because we can see the light only when it hits an object and bounces off of it.
35. Neptune has a moon named Triton and is the coldest known object in the solar system.
36. The Sun is white because of its extreme heat (10,340.33 degrees F). It only appears yellow be-cause of the Earth’s atmosphere.
