- 11. Way Galaxy the spiral shaped galaxy in which we live
- 13. a meteor that hits or lands on Earth’s surface; very small, cause little damage, and usually only weigh a few pounds
- 16. Moons the 4 largest moons of Jupiter - Io, Europa, Ganymede, and Callisto
- 19. Climate A climate that stays fairly consistent over a long period of time without extreme changes in temperature or weather patterns.
- 20. The ability of a planet or environment to support and maintain life.
- 22. a loose ball of ice and rock that usually has a long, narrow orbit around the sun
- 24. belt a collection of small, icy objects located in a doughnut-shaped ring in a region of space located past Neptune

Down
- 1. Attraction force of attraction between two objects due to their mass and distance. Larger objects, like planets and stars, have stronger gravity.
- 2. using resources in a way that meets current eeds while protecting them for future generations.
- 5. System consists of a star and everything that orbits that star
- 6. Planets the last four planets in the solar system referred to as the “gas giants” - Jupiter, Saturn, Uranus, and Neptune
- 7. Conditions The best possible environmental conditions needed for something to survive, grow, or fimctopm we;;/
- 9. the spinning of a planet or a moon on its axis
- 12. a small, mostly rocky or metallic body that orbits the sun in the inner solar system
- 14. Orbit The oval-shaped path an object follows as it moves around another object in space, like Earth orbiting the sun.
- 15. one complete trip of a planet around the Sun
- 17. a small piece of matter from outer space that becomes a streak of light when it falls through Earth’s atmosphere and burns up also known as a “shooting star”
- 18. zone the distance from a star at which liquid water could exist on orbiting planets' surfaces
- 21. a rocky object that orbits the Sun; composed of metals nickel and iron; much smaller in size than asteroids
- 23. cloud most distant region of our solar system
