Is the sun really a dwarf star?

Despite being 865,000 miles across, the sun is classified as a "dwarf star" — specifically a G2V main-sequence star where the "V" designation indicates dwarf status. This classification system is based on temperature and mass rather than absolute size, with G-type stars ranging from yellow to white and representing about 90-110% of the sun's mass. The sun will maintain its dwarf classification until it exhausts its hydrogen fuel in approximately 5 billion years and expands into a red giant.
