A star system is a group of planets, meteors, or other objects that orbit a large star. While there are many star systems, including at least 200 billion other stars in our galaxy, there is only one solar system. That's because our sun is known by its Latin name, Sol.
The solar system includes everything that is gravitationally drawn into the sun's orbit. Astronomers have discovered there are many other large stars within our galaxy, the Milky Way. Use these resources to teach students about the objects and relationships within our solar system.
