Millions of light-years Mpc M m - Milky Way: SBbc ... Ursa Major II Dwarf: dSph 0.098 0.030 ... Closest spiral galaxy to Local Group
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 ...
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 Large Magellanic Cloud (LMC) is a dwarf galaxy and satellite galaxy of the Milky Way. [7] At a distance of around 50 kiloparsecs (163,000 light-years), [2] [8] [9] [10] the LMC is the second- or third-closest galaxy to the Milky Way, after the Sagittarius Dwarf Spheroidal (c. 16 kiloparsecs (52,000 light-years) away) and the possible dwarf irregular galaxy called the Canis Major Overdensity.
It is located 4 degrees below the Galactic plane, and, at a distance of 4.0 Mpc (13 Mly), is one of the closest major galaxies to the Milky Way. [3] The galaxy is undergoing tumultuous changes, as rings of gas are likely being ejected from the galaxy. [4] Its outermost ring is 1400 light-years across while the inner ring is 260 light-years across.
The find, announced Wednesday, can help explain how solar systems across the Milky Way galaxy came to be. This one is 100 light-years away in the constellation Coma Berenices. A light-year is 5.8 ...
Sgr dSph is roughly 10,000 light-years in diameter, and is currently about 70,000 light-years from Earth, travelling in a polar orbit (an orbit passing over the Milky Way's galactic poles) at a distance of about 50,000 light-years from the core of the Milky Way (about one third of the distance of the Large Magellanic Cloud).
