  1. 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.
  2. 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.
  3. 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.
  4. 7. Our home planet, Earth, is the only known planet to support life. It has oceans, mountains, forests, and a diverse range of ecosystems.
  5. 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.
  6. 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.
  7. 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.
  8. 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.
  9. 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.

  1. 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.
  2. 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.
  3. 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.
  4. 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.
  5. 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.
  6. 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.
