Difference between stars, galaxies, nebulae, planets, and moons?

Question

Thanks!!!

Answer 1

Stars are huge balls of gas and plasma, with internal nuclear fusion producing energy, which the surface radiates partially as light. A galaxy is a collection of millions of stars (ours has an estimated 400,000,000,000). Before we had good telescopes, the small, fuzzy patches of light we could see in the night sky were called nebulae. A planet is a large spheroidal body of matter, usually orbiting a star, whereas a moon is a smaller and orbits a planet.

Answer 2

Starts are like our Sun. Galaxies are groups of stars. Our sun is in the Milky Way Galaxy. Nebulae are in the process of becoming stars, like a birth. Planets orbit stars, though mosth stars do not have planets. Moons orbit planets.
