Proxima Centauri
Proxima Centauri is a M-type (Red) star located in the constellation Centaurus.
At a distance of approximately 4.23 light-years, Proxima Centauri is one of the Sun's closest stellar neighbors. Light that we observe from Proxima Centauri today left the star roughly 4 years ago, making it a near neighbor in galactic terms.
Proxima Centauri is classified as a spectral class M star (M-type (Red)) on the Harvard spectral classification system.
At an apparent magnitude of +11.01, Proxima Centauri is a faint star that requires a telescope to observe. It is invisible to the naked eye and too dim for most binoculars. Observers will note its red hue, which corresponds to a B-V color index of +1.807.
