The Sun is the star at the center of the Solar System. It is almost perfectly spherical and consists of hot plasma (state of matter) interwoven with magnetic fields. It has a diameter of about 1,392,000 km, about 109 times that of Earth, and its mass (about 330,000 times that of Earth) accounts for about 99.86% of the total mass of the Solar System. Scientists calculate our Sun and solar system formed at the same time - a whopping 4.56 billion years ago.
