Detailed explanation-1: -About 90 percent of the stars in the universe, including the sun, are main sequence stars. These stars can range from about a tenth of the mass of the sun to up to 200 times as massive. Stars start their lives as clouds of dust and gas.
Detailed explanation-2: -The Sun is categorized as a main sequence star, that is, it fuses Hydrogen atoms into Helium atoms to produce its energy. Within this astronomical classification, the Sun is considered a yellow dwarf star.
Detailed explanation-3: -The Sun is currently a main sequence star and will remain so for another 4-5 billion years. It will then expand and cool to become a red giant, after which it will shrink and heat up again to become a white dwarf.
Detailed explanation-4: -The Sun is a G-type main-sequence star (G2V). As such, it is informally, and not completely accurately, referred to as a yellow dwarf (its light is actually white). It formed approximately 4.6 billion years ago from the gravitational collapse of matter within a region of a large molecular cloud.
