These activities will help students understand where the sun is in the solar system and how big the earth, moon, and sun are. Describe the appearance of Earth and the moon. A star is a ball of hot, burning gases. The sun is the closest star to Earth (about 150,000,000 km/93,000,000 miles) away. Therefore, it looks bigger and brighter to those on Earth than other stars. Earth spins on an imaginary line called an axis. A complete rotation takes about 24 hours (one day).
