Detailed explanation-1: -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).
Detailed explanation-2: -Some other examples of the yellow dwarf star group include Alpha Centauri, Tau Ceti and 51 Pegasi. For the quick answer, the Sun is a Population I yellow dwarf star, in the main sequence.
Detailed explanation-3: -The Sun is a main sequence star with a G spectral type, or a yellow dwarf star.
Detailed explanation-4: -In our case, our Sun releases the energy that we see as sunlight on Earth. So, it burns hydrogen into helium and releases energy. Typically, stars go through this “main sequence” for about 95% of its life. So for most of our sun’s life, it releases energy as sunlight through thermonuclear reactions.
