The mass of either galaxy is difficult to estimate with any accuracy, but it was long thought that the Andromeda Galaxy was more massive than the Milky Way by a margin of some 25% to 50%. [11] However, this has been called into question by early-21st-century studies indicating a possibly lower mass for the Andromeda Galaxy [ 11 ] and a higher ...
Messier 32 (also known as M32 and NGC 221) is a dwarf "early-type" galaxy about 2,490,000 light-years (760,000 pc) from the Solar System, appearing in the constellation Andromeda. M32 is a satellite galaxy of the Andromeda Galaxy (M31) and was discovered by Guillaume Le Gentil in 1749. The galaxy is a prototype of the relatively rare compact ...
The interstellar dust in M110 has a mass of (1.1–1.8) ... The Andromeda Galaxy and its satellite galaxy, Messier 110, to the bottom-right of the center.
The Andromeda Galaxy with M110 at upper left and M32 to the right of the core. The Andromeda Galaxy (M31) has satellite galaxies just like the Milky Way.Orbiting M31 are at least 13 dwarf galaxies: the brightest and largest is M110, which can be seen with a basic telescope.
It has an estimated mass-loss rate of 0.0017 M ... Theoretical limit of star size (Andromeda Galaxy) ≳1,750 [9] L/T eff:
The term "The Local Group" was introduced by Edwin Hubble in Chapter VI of his 1936 book The Realm of the Nebulae. [11] There, he described it as "a typical small group of nebulae which is isolated in the general field" and delineated, by decreasing luminosity, its members to be M31, Milky Way, M33, Large Magellanic Cloud, Small Magellanic Cloud, M32, NGC 205, NGC 6822, NGC 185, IC 1613 and ...
Andromeda Galaxy: Andromeda: Andromeda, which is shortened from "Andromeda Galaxy", gets its name from the area of the sky in which it appears, the constellation of Andromeda. [citation needed] Andromeda is the closest big galaxy to the Milky Way and is expected to collide
It is located 130,000 light-years (40 kpc) [3] from the Andromeda Galaxy's galactic core, and is the brightest [3] (by absolute magnitude) globular cluster in the Local Group, with an absolute visual magnitude of −10.94 and the luminosity of 2 million Suns. [4] It has an apparent magnitude of 13.81 in V band.
