Our sun is the largest and most massive object in the solar system.
It's more than 100 Earths wide and could theoretically fit all eight planets inside nearly 600 times.
It also contains approximately 99.8% of all the mass in the solar system.
Because of this mass, the sun has a great pull on the fabric of space, creating a gravitational force that causes nearby planetary bodies to be drawn toward it.
This gravitational pull allows the sun to hold together a system of eight planets, potentially dozens of dwarf planets, at least 170 moons, and countless comets and asteroids.
