Messier 105 or M105, also known as NGC 3379, is an
Helen S. Hogg found a letter by Méchain locating and describing this object which matched those aspects under its first-published name, NGC 3379.[9]
It has a
ellipticity of no more than 0.06. There is no fine structure apparent in the isophotes, such as ripples.[10] Observation of giant stars in the halo indicate there are two general populations: a dominant metal-rich subpopulation and a weaker metal-poor group.[3]
Messier 105 is known to have a
emission line ratios between a LINER and a H II region.[12] The galaxy also contains a few young stars and stellar clusters, suggesting some elliptical galaxies still form new stars, but very slowly.[13]
This galaxy, along with its companion the
Messier objects of which are M95 and M96.[15][16][17][18] It is one of the richest group of galaxies in the Local Volume, and unlike the Local Group, it is dominated by not one but several galaxies.[19]
