Solar System

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.
