Across
  1. 3. Features made of ice and rock dust that are found around all of the outer planets.
  2. 6. One of the two specific moons that orbits the planet Mars.
  3. 8. The force that pulls dust and gas inward, causing a giant cloud to shrink and collapse.
  4. 9. The process where an element turns from a gas into a liquid due to low temperatures.
  5. 10. The inner planet described as a heavy metal ball with a thin rocky crust.
  6. 14. The biggest planet in our solar system, also known as the Gas King.
  7. 15. The farthest and coldest planet in our solar system, which experiences the strongest winds.
  8. 16. The sideways ice world that uniquely rotates on its side.
  9. 19. The full name of the measurement unit that represents the average distance from the Earth to the Sun.
  10. 21. The term for substances like water, methane, and ammonia that freeze into solid ice particles past the frost line.
  11. 25. The minimum speed needed for a gas particle to break free from a planet's gravitational pull.
Down
  1. 1. One of the lighter gases that makes up ninety-two percent of the total planetary mass of Jupiter and Saturn.
  2. 2. The material found heavily in the soil of Mars that gives it a red, rusty look.
  3. 4. A constant stream of high-energy particles blown outward into space from the Sun.
  4. 5. The layer of surrounding gases that was stripped away from inner rocky planets by intense solar heat and wind.
  5. 7. The planet group composed of metal and rock with solid crusts.
  6. 11. The planet nicknamed the Water World because it contains liquid water and supports life.
  7. 12. The specific part of the collapsed interstellar cloud that becomes hot enough to spark nuclear reactions.
  8. 13. A planet with famous rings of ice and rock that is so light it could float in a pool.
  9. 17. The specific distance in a solar system past which water, ammonia, and methane freeze into solid ice particles.
  10. 18. The planet nicknamed the Rusty Planet because it has lots of iron in its soil.
  11. 20. A vast interstellar cloud of dust and gas where solar system formation begins.
  12. 22. The gas that absorbs red light and gives Neptune its deep blue hue.
  13. 23. The hottest world in our solar system with a thick, choking atmosphere that traps heat.
  14. 24. The alternative scientific group name given to the Outer Giants.
