of NGC 147, NGC 185, NGC 205, M32, M33 and
M31.
The entire Local Group appears to be an out-riding
member of a super clustering of galaxies centered on
the more distant Virgo Cluster (see Supergalaxy). The
local group contains a rather typical distribution of
types of galaxies and extends over a volume 1 mega
parsecs in diameter. The group contains three spiral
galaxies, each about 15 to 50 kilo parsecs in
diameter: the Milky Way, Andromeda, and the
Triangulum Nebula (M33). There are four irregular
galaxies of some 3 to 10 kilo parsecs across,
including the large and Small Magellanic Clouds. The
other galaxies are ellipticals, including 4 regular
ellipticals, 2 to 5 kilo parsecs across, two of which are
the companions to the Andromeda galaxy. The
remaining members are dwarf ellipticals, mostly less
than 2 kilo parsecs across.
By far, the largest members of the Local Group are
the Andromeda galaxy (M31) and our own Milky Way.
Both are super-giant-spiral galaxies and the center of
mass for the entire group is located along a line
connecting the two, about 2/3 of the distance from our
galaxy toward M31. It is believed that both M31 and
our own galaxy are in a very slow orbit about the
common barycenter. M31 (Andromeda) is both larger
and brighter than our galaxy by about 50 per cent.
In addition to galaxies, the Local Group contains a
number of intergalactic globular clusters, some of
which may be out-riding members of our own galaxy.
The cluster NGC 5694 appears to be moving through
our galaxy in a hyperbolic orbit and can therefore be
considered a true "intergalactic tramp." The known
dwarf spheroidal galaxies and intergalactic clusters
are mostly located rather close to the galaxy. The
