  1. Our sun is a magnificent, life-giving force. While it's only considered a medium star by universal standards, thanks to our proximity to it, the sun supplies us with heat and light. It is the most basic source of energy for planet Earth; without it, neither people nor any other species would be able to survive. The sun is 1.3 million times larger than Earth. Because the sun is so big, it also produces a lot of gravity. The sun's strong gravitational pull is what keeps Earth and the other planets in our solar system in orbit.
