BE Camelopardalis is a solitary[10] variable star in the northern circumpolar constellationofCamelopardalis. It is visible to the naked eye as a faint, red-hued point of light with an apparent visual magnitude that fluctuates around 4.39.[3] The star is located roughly 800 light years away from the Sun based on stellar parallax.[2]
This object is an M-type bright giant with a stellar classification of M2 II,[6] and is currently on the asymptotic giant branch. It is classified as an irregular variable of subtype Lc and its brightness varies from magnitude +4.35 down to +4.48.[4] Having exhausted the supply of hydrogen at its core, the star has expanded to around 176[8] times the Sun's radius. It has 2.9[7] times the Sun's mass and is radiating over four thousand times the luminosity of the Sun from its enlarged photosphere at an effective temperature of 3,615 K.[8]
