Which object travels around another object in space?

Which object travels around another object in space?

• A. Meteoroid
• B. Comet
• C. Satellite
• D. Galaxy

Answer: (C)

Objects in space can stay in orbit around a larger body when gravity pulls them toward the center of mass. A satellite is defined as anything that travels around another object because of that gravitational pull. The Moon is a natural satellite of Earth, and the International Space Station is an artificial satellite orbiting Earth, both following curved paths rather than moving in a straight line or drifting away. A meteoroid is a small rock floating in space and doesn’t imply orbit. A comet moves around the Sun in an elongated orbit, not around a planet. A galaxy is a huge system of stars and other matter, not something that generally travels around another object in the sense of an orbiting satellite. So, the best fit is a satellite.
