TheSun is thestar at the center of theSolar System. It is a nearly perfectsphere of hotplasma, heated toincandescence bynuclear fusion reactions in its core, radiating energy from itssurface mainly aslight andinfrared radiation. It is aG-type main-sequence star (G2V), informally called a yellow dwarf, though its light is actually white. It formed about 4.6 billion years ago and is by far the most important source of energy forlife onEarth. From Earth the Sun is 1 astronomical unit (1.496×108 km) or about 8light-minutes away.Its diameter is about 1,391,400 km (864,600 mi), 109 times that of Earth.Its mass is about 330,000 times that of Earth, making up about 99.86% of the total mass of the Solar System. Every second, the Sun fuses about 600 billionkilograms (kg) of hydrogen into helium and converts 4 billion kg ofmatter into energy.Venerated in many cultures, it is a central subject for astronomical research sinceantiquity.(This article is part of afeatured topic:Solar System.)
