Antares (Alpha Scorpii) is a huge red hypergiant star, with a radius 800 times that of our own sun. There are some bigger stars though, such as Betelgeuse (1180 solar radii) and V354 Cephei (1520 solar radii), but the biggest known star is VY Canis Majoris, which is estimated to have a diameter between 1800 and 2100 times that of our own sun. If it were in the centre of our solar system its edges would almost reach the orbit of Saturn.
