That's a great question! What you're describing is called a solar system.

Here's a breakdown:

* Star: The central, massive object in a solar system, like our Sun. It's a giant ball of hot gas that produces its own light and heat through nuclear fusion.

* Bodies in orbit: These can include planets, moons, asteroids, comets, and even dust and gas.

* Orbit: The path that these bodies take around the star, influenced by the star's gravity.

So, a solar system consists of a star and all the objects that are gravitationally bound to it and orbiting it.
