Almaaz

Almaaz (better known as Epsilon Aurigae) is a yellow-white supergiant star in the constellation Auriga. It has a smaller blue main sequence star companion, dubbed Almaaz B or Epsilon Aurigae B. Almaaz A is a very historically important star, as in 1940 it was crowned as the largest star, with a radius of 2,400 Solar Radii at the time. It… Continue reading Almaaz

KY Cygni

KY Cygni is a red hypergiant star in the constellation Cygnus. It is one of the largest known stars, with a radius of over 1,032 Solar Radii. It would be one of the brightest stars in the night sky if it weren’t for the dust surrounding it. KY Cygni also boasts a slow irregular variable star designation. KY Cygni is… Continue reading KY Cygni

Rigil Kentaurus

Rigil Kentaurus (sometimes spelt Rigil Kentavrus and better known as Alpha Centauri A) is a yellow main sequence star in the constellation Centaurus. It is the third brightest star in the night sky, as well as the brightest star within its constellation. It is a binary with Toliman, which the two stars form a trinary with Proxima Centauri. The Alpha… Continue reading Rigil Kentaurus

Toliman

Toliman (better known as Alpha Centauri B and also called Proksima Kentavra) is an orange dwarf star in the constellation Centaurus. It is the second nearest star to the sun and is part of the trinary star system Alpha Centauri. On its own, Toliman ranks at #21 of brightest stars in the night sky on average. Toliman and Rigil Kentaurus… Continue reading Toliman

Proxima Centauri

Proxima Centauri is a red dwarf star in the constellation Centaurus. It is the nearest star to the Sun with only a distance of 4.24 Light Years. Proxima Centauri is a flare star, a star that changes brightness unpredictably. Its name in Latin means “The Nearest Star of Centaurus.” It was discovered in 1915 by Robert Innes. Proxima Centauri has… Continue reading Proxima Centauri
