Which term describes a system involving objects interacting with the Sun?

• A. Solar System
• B. Milky Way
• C. Universe
• D. Nebula

Answer: (A)

The key idea is a gravitationally bound group of bodies that orbit a central mass. In our case, the Sun is the central mass and the planets, moons, asteroids, comets, and other objects orbit it, forming the solar system. This setup—objects interacting with and kept in orbit by the Sun’s gravity—defines the term. The Milky Way, while it contains the Sun and many other stars, is a galaxy, not a system organized around the Sun. The Universe includes everything—galaxies, stars, planets, and all matter and energy. A nebula is a cloud of gas and dust where stars can form, not a planetary system bound to the Sun.
