- 3. A body in outer space, made of hot gases, that shines in the night sky.(Our Sun is one of these!)
- 6. A planet with large rings around it that is sixth from the Sun; a gas giant.
- 7. The area in space between Mars and Jupiter where most asteroids orbit together. It will not help hold up your pants!!
- 9. A single turn of something around an axis or a fixed point; spinning. (It takes Earth 24 hours)
- 12. The smallest planet in our solar system and the closest to the Sun; a terrestrial planet.

- 17. A space object made of ice and dust that orbits a star and develops
- 18. The largest planet in our solar system and the fifth from the Sun; a gas giant.
Down
- 1. A large blue planet that is eighth from the Sun; a gas giant.
- 4. An area of our solar system beyond the orbit of Neptune where a group of minor planets and other objects orbit the Sun.
- 5. The center of an object. (Think about an apple.)
- 8. a nearly round object that orbits a star,
- 10. is smaller than a planet, and is not a satellite of another object. (Think…Pluto!)
- 11. This means to revolve around another object. Our Moon does this to Earth.
- 13. A layer of gases surrounding a planet, star, or moon.
- 15. A dwarf planet that was discovered in 1930 and that was once considered a planet.
