Short answer: there is one star in our Solar System—the Sun. Details

• Core fact: The Solar System consists of the Sun and all objects bound to it by gravity (planets, moons, asteroids, comets, etc.). The Sun is the only star in this system.

• Clarifying context: When people refer to “stars in the Solar System,” they’re typically asking how many stars the system contains. By definition, the Sun is a star, and there are no other stars orbiting the Sun within the Solar System.

• Related notes: Our Milky Way galaxy hosts a vast number of stars (on the order of 100 billion or more), but that is separate from the Solar System itself. Exoplanet discoveries show many planets around other stars in our galaxy, not within our Solar System.
