Proxima Centauri red dwarf star. Animation of the location in the night sky and the properties of the M-type red dwarf star Proxima Centauri (Alpha Centauri C), 4.25 light years from Earth in the constellation of Centaurus. Proxima Centauri is a main sequence star, 0.14 times the width of the Sun (over 190, 000 kilometres across) and 0.12 times the Sun's mass. Proxima Centauri has two distant companion stars (the binary system Alpha Centauri A and Alpha Centauri B), forming the closest star system to Earth. Proxima Centauri is around 5 billion years old. It has a very low rate of energy expenditure, meaning it will continue to shine for another 4 trillion years. Proxima Centauri is spectral type M6, with a luminosity class of Ve. It has a luminosity 0.0017 times that of the Sun, and has an atmospheric temperature of 3042 Kelvin. Its spectrum has strong titanium oxide lines and some calcium lines. | |
