Greek Name: Helios -- Roman Name: Sol
The Sun is 860,000 miles in diameter, it is by far the largest object in the solar system. It contains 99.8% of the mass of the solar system. The suns energy output is around 386 billion billion megawatts, it is produced by nuclear fusion reaction. Every second about 700 million tons of hydrogen are converted into about 695 million tons of helium, producing about 5 million tons of energy in the form of gamma rays.

Asteroids are rocky metallic objects, left over from the formation of the solar system. Some Astronomers believe that asteroids are the remains of a Protoplanetary that was destroyed in a massive collision long ago, the popular view is that asteroids are leftover rocky matter that never successfully coalesced into a planet. Most asteroids orbit the sun between Mars and Jupiter, and some past Saturn. Some are known to orbit inside of Earths orbit, these are known as Near Earth Objects or NEO's.

The Kuiper belt was just a theory until 1992 when astronomers became aware of a vast number of small bodies orbiting the sun beyond Neptune at 30 to 50 AU's. Also know as the Oort cloud, it is thought that long period comets come from this cloud when they are perturbed by the gas giants like Jupiter or Saturn, they can also be perturbed by a passing star. Although the closet star is 4.5 light years away, its gravity reaches billions of miles.
