The Sun is a giant ball of mostly hydrogen gas. It’s
extraordinarily massive — about 300,000 times as massive as Earth — and
tremendous powerful. The Sun gives off what most people would call an
unfathomable amount of energy, but in scientific notation, it’s about 4 x
1026 Watts, which is at least fathomable, although it’s
absolutely tremendous. This means that even at the surface of the
Earth, 150 million kilometers away, that means we have 129 Watts of
solar energy striking us over every square foot that receives sunlight.
