The Triangulum Galaxy (M33) is the third-largest member of the Local Group, with a mass of approximately 5 × 10 10 M ☉ (1 × 10 41 kg), and is the third spiral galaxy. [6] It is unclear whether the Triangulum Galaxy is a companion of the Andromeda Galaxy; the two galaxies are 750,000 light years apart, [ 7 ] and experienced a close passage 2 ...

Groups are the most common structures of galaxies in the universe, comprising at least 50% of the galaxies in the local universe. Groups have a mass range between those of the very large elliptical galaxies and clusters of galaxies. [5] Our own galaxy, the Milky Way, is contained in the Local Group of more than 54 galaxies. [6]
The largest in the Cartwheel Galaxy group, made up of four spiral galaxies [citation needed] Cigar Galaxy: Ursa Major: Appears similar in shape to a cigar. [citation needed] Also known as Messier 82 or M82 [citation needed] Circinus Galaxy: Circinus: Named after the constellation it is located in . [citation needed] Cocoon Galaxy: Canes Venatici

Four of the seven members of galaxy group HCG 16 [1]. A galaxy group [2] or group of galaxies [3] (GrG [4]) is an aggregation of galaxies comprising about 50 or fewer gravitationally bound members, each at least as luminous as the Milky Way (about 10 10 times the luminosity of the Sun); collections of galaxies larger than groups that are first-order clustering are called galaxy clusters. [5]
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 ...
The Milky Way galaxy is a member of an association named the Local Group, a relatively small group of galaxies that has a diameter of approximately one megaparsec. The Milky Way and the Andromeda Galaxy are the two brightest galaxies within the group; many of the other member galaxies are dwarf companions of these two. [176]
