The Andromeda Galaxy is a barred spiral galaxy and is the nearest major galaxy to the Milky Way. It was originally named the Andromeda Nebula and is cataloged as Messier 31, M31, and NGC 224. Andromeda has a D 25 isophotal diameter of about 46.56 kiloparsecs (152,000 light-years) [8] and is approximately 765 kpc (2.5 million light-years) from ...
Nearest galaxy to the Milky Way Sagittarius Dwarf Spheroidal Galaxy: 1994 0.070 Mly The closest, undisputed galaxy. The disputed dwarf galaxy Canis Major Overdensity is even closer at 25,000 light-years.

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 ...

The Milky Way galaxy consists of several hundred billion stars, including our sun. If the skies are clear, it’s possible to see those stars in the southern sky right after sunset.
Combined with its absolute magnitude of only +2.2, this makes it by far the Milky Way's dimmest satellite, and only about as bright as Altair. This absolute magnitude corresponds to a total luminosity of 11.4 L ☉. [1] Ursa Major III is predicted to have a mass-to-light ratio of about 6,500. However, this becomes only 1,900 with the removal of ...
The Milky Way has several smaller galaxies gravitationally bound to it, as part of the Milky Way subgroup, which is part of the local galaxy cluster, the Local Group. [ 1 ] There are 61 small galaxies confirmed to be within 420 kiloparsecs (1.4 million light-years ) of the Milky Way, [ 2 ] but not all of them are necessarily in orbit, and some ...
