It is also designated α Carinae, which is romanized (transliterated) to Alpha Carinae. With a visual apparent magnitude of −0.74, it is outshone only by Sirius . Located around 310 light-years from the Sun , Canopus is a bright giant of spectral type A9 , so it is essentially white when seen with the naked eye.
