Document Summary
A planet is a large solid body orbiting a star (the sun) and has a spherical shape. Has cleared it neighborhood of other objects by gravity. Moon is a solid body locked in orbit around a planet. Two groups of planets---terrestrial planets are small rocky (mercury venus earth mars) Astroid belt between the two types gas giant planets are large low density (jupiter science uranus neptune) The earth is orbiting the sun as well as on its own axis figured out by liam. The pendulum swings back and forth in the same place and the earth rotation moves the ground below the pendulum. Light and heat derives from nuclear fusion reactions. We are in the milky way and it contains over 300 million stars including the sun. The speed of light is (c) 186,000 miles / s. the moon is 1. 3 light seconds (230,00miles).
