Gravity is a function of mass.
To be more precise:
Gravity is the means by which objects with mass attract one another.
The sun has a mass that is 330,000 times the mass of the Earth.
The sun is a gravitational monster! The gravity of the sun is so powerful that other objects of massive gravity, such as the Earth, are attracted to it and surround it.
We call it orbit.
