Supergiants are some of the largest stars in the universe. They are larger than giant stars, and less luminous than hypergiants. They vary greatly in size. Some are only 50 million kilometers across, small enough to fit inside the orbit of Venus. Some are 2,700 million km across, as wide as the orbit of Neptune.
