M Carinae (HD 88981) is a solitary star in the constellation Carina. It has an apparent magnitude of +5.154,[1] making it faintly visible to the naked eye under ideal and is located approximately 310[2] light-years from Earth. With a heliocentric radial velocity of Шаблон:Val[3] M Carinae is drifting closer to the Solar System.

M Car has a stellar classification of kA8 mF4 III[4] which indicates that it has the calcium K-line and surface temperature of an A8 star and the metallic lines of an evolved F-type giant that has just exhausted hydrogen fusion at its core. At present M Car has 2.14[5] times the mass of the Sun but has mildly expanded to 4.45 times its girth. It shines at a luminosity almost 63 times greater than the Sun from its bloated photosphere at an effective temperature of Шаблон:Val, [2] which gives it the white glow of an A-type star. M Car spins moderately at a projected rotational velocity of Шаблон:Val,[6] slightly faster than most Am stars.
