View Full Version : Three Largest Stars Discovered

2005-Sep-10, 11:55 AM
SUMMARY: Astronomers have found three red supergiant stars which are huge; bigger than anything previously discovered. The three stars are called KW Sagitarii (9,800 light-years away), V354 Cephei (9,000 light-years away), and KY Cygni (5,200 light-years away). All three are 1,500 times bigger than our own Sun, and would reach out midway between Jupiter and Saturn if they were in our Solar System. These stars aren't extremely massive, though, they're only 25 times the mass of the Sun (stars have been discovered which have 150 times the mass of the Sun).
