Star A star has its own light. Stars twinkle at night. The relative positions of the stars do not undergo any noticeable change. Since the stars are very far away, the telescope can only make them look brighter but not larger. A star has very high temperature. There are billions of stars in the celestial sphere. Planet A planet has no light of its own. It shines by reflecting the light of the sun. Planets do not twinkle. Since planets are very mush closer to the earth than the stars are, their motion around the sun is noticeable as a daily shifting of their relative positions in the sky. Most planets on the other hand are near enough to the earth to be magnified by the telescope. Planets have low temperatures. There are only nine planets in the solar system.
