The Sun is the largest object in our solar system, comprising 99.8% of the system’s mass. Though it seems huge to us, the Sun isn't as large as other types of stars.

Earth orbits the Sun from a distance of about 93 million miles. The connection and interactions between the Sun and Earth drive our planet's seasons, ocean currents, weather, climate, radiation belts, and aurorae. Though it is special to us, there are billions of stars like our Sun scattered across the Milky Way galaxy.
