Which natural object orbits a planet?

Which natural object orbits a planet?

• A. Moon
• B. Star
• C. Asteroid
• D. Comet

Answer: (A)

Objects that orbit a planet under gravity are natural satellites. The Moon is Earth's natural satellite because it stays bound to our planet and orbits around it. This relationship is what defines a moon: a body that completes an orbit around a planet. A star, on the other hand, is a massive luminous object that belongs to a star system or a galaxy, not something that orbits a planet. Asteroids and comets mostly travel around the Sun, and only rarely get captured into a temporary orbit around a planet; they aren’t considered permanent natural satellites of a planet like the Moon is.
