1. There are more stars in the universe than grains of sand on Earth.
2. One million Earths could fit inside the Sun, and the Sun is considered an average-sized star.
3. Martian sunsets would appear bluish to human observers watching from the red planet.
4. One day on Venus is longer than one year. Venus takes 243 Earth days to complete a rotation. The orbit of Venus around the Sun is 225 Earth days.
5. At present, the biggest known star is Stephenson 2-18. An enigmatic red supergiant in the constellation Scutum.
6. The dot in between is our solar system, compared to the biggest known black hole, Phoenix A.
7. 99.86% of our solar system's mass is the Sun.
8. Space isn't completely silent. It's lively with charged particles that, with the right tools, we can hear.
9. Astronaut literally means "Star Sailor" in Greek. Astro is derived from ástron, meaning “star.” Naut is derived from naútēs, meaning sailor.
10. It takes 225 million years for our Sun to revolve around the Milky Way. The Milky Way is glued together by a supermassive black hole at its center called Sagittarius A*.
11. There are more trees on Earth than there are stars in our entire galaxy.
12. The Moon gets its light from the Sun. The light from the Sun bounces off of the moon's surface and reaches the Earth.
13. The fastest-spinning neutron star, known as PSR J1748–2446ad, rotates at a rate of 716 times per second.
14. Black holes rotate at nearly the speed of light! Many black holes are spinning at more than 90% of the speed of light.
15. A year on Neptune is about 165 Earth years long. The planet has only completed one orbit around the Sun since it was discovered in 1846.
16. According to the theory of flotation, Saturn can float on water like ice. Saturn has a density of 0.7 g/cc, which is less than the density of water, 1 g/cc.
17. Astronomers have discovered a massive reservoir of water in the universe in vapor form. The water is equivalent to 140 trillion times the amount of water in the world's oceans.
18. The Andromeda galaxy will collide with our Milky Way galaxy. This collision is predicted to occur in about 4.5 billion years.
19. The largest known structure in the universe is the Hercules-Corona Borealis Great Wall. A massive cluster of galaxies is approximately 10 billion light-years in length!
20. Uranus has 27 moons. 25 of them are named after Shakespeare's characters. The other 2 moons are named after characters from Alexander Pope's works.
