The sun is the real star of the solar system. It is the closest star to Earth and is the source of all the heat and light on Earth. Life wouldn’t exist without it. It's also the center of our solar system and by far its largest object. More than a million Earths would fit inside the sun! Our star’s enormous gravity grips the planets, dwarf planets, asteroids, comets, keeping them from spinning into deep space. Put simply, we wouldn’t have a solar system without the sun.
