Only one star, HIP 21158 in Taurus, remains a candidate sibling; however, the evidence that this star was born in the same cluster as the Sun is weak.
The Sun is a star with a diameter of approximately 864,000 miles (1,390,000 kilometers), about 109 times the diameter of Earth. The largest stars have a diameter about 1,000 times that of the Sun.
