- 2. Pluto used to be considered the ninth planet in our solar system but was reclassified as a dwarf planet. It is very cold and far from the Sun.
- 3. Io is one of Jupiter's moons and is known for its volcanic activity. It has over 400 active volcanoes and is the most geologically active body in our solar system.
- 5. Europa is one of Jupiter's moons and is covered in ice. Scientists believe that beneath the icy surface, there might be a vast ocean of liquid water, which could potentially harbor life.
- 7. Our home planet, Earth, is the only known planet to support life. It has oceans, mountains, forests, and a diverse range of ecosystems.
- 9. The closest planet to the Sun, Mercury is very hot during the day and extremely cold at night. It has a rocky surface and no atmosphere.
- 10. Neptune is a blue planet that is similar to Uranus. It is also a gas giant and has a storm called the Great Dark Spot, which is similar to Jupiter's Great Red Spot.
- 11. Venus is often called Earth's "sister planet" because it is similar in size. It has a thick atmosphere and is covered in clouds. It is the hottest planet in our solar system.
- 12. Ganymede is the largest moon in our solar system and belongs to the planet Jupiter. It is even larger than the planet Mercury. It has a frozen surface with cracks and ridges.
- 14. Ceres is the largest object in the asteroid belt between Mars and Jupiter. It is considered a dwarf planet and is made up of rock and ice.
Down
- 1. Jupiter is the largest planet in our solar system. It is a gas giant and has a storm called the Great Red Spot, which is a giant swirling storm that has been raging for centuries.
- 4. Titan is Saturn's largest moon and has a thick atmosphere. It is the only moon in our solar system with a significant atmosphere. It also has lakes and rivers of liquid methane.
- 5. Enceladus is another moon of Saturn and has geysers that shoot out water vapor into space. Scientists have detected organic molecules and believe it may have conditions suitable for life.
- 6. Saturn is known for its beautiful rings made up of ice, rock, and dust particles. It is a gas giant and has many moons.
- 8. Uranus is an icy planet that is tilted on its side. It is unique because it rotates on its side compared to other planets. It is also a gas giant.
- 13. Known as the "Red Planet," Mars has a rusty, reddish appearance. It has polar ice caps and a thin atmosphere. Scientists are studying Mars to learn more about its potential for supporting life.
