• An asteroid is a rocky body that orbits the sun between Mars and Jupiter.
• A meteorite is a piece of space debris that enters the earth's atmosphere and falls back down to the ground.
• Uranus has an unusual tilt that causes it to rotate on its side
• Asteroids are rocky objects that orbit between Mars and Jupiter
• Uranus is tilted on its side so it appears to rotate at an angle
• Ganymede orbits Jupiter
• Mercury is the closest planet to the sun
• The sun is the center of our solar system, with all planets revolving around it
• Mars has two small moons called Phobos and Deimos.
