Which statement describes the Sun's classification on the main sequence best?

• A. Red Giant
• B. Yellow Main Sequence
• C. White Dwarf
• D. Blue Giant

Answer: (B)

On the main sequence, a star’s position is set by its surface temperature and color. The Sun’s surface temperature is about 5,800 kelvin, which gives it a yellowish hue. That places it in the middle of the main-sequence band as a G-type star, commonly described as a yellow main-sequence star (yellow dwarf). It stays on this stable hydrogen-burning path, unlike red giants that have expanded after leaving the main sequence, white dwarfs which are compact remnants, or blue giants which are hot, massive stars much hotter than the Sun. So describing the Sun as a yellow main sequence star is the best fit.
