M32 = NGC221 ( 0h 42.7m +40°52´, 8.2 mag. )
This dwarf elliptical galaxy is a satellite of Great Andromeda Galaxy (M31) and was discovered by LeGentil in 1749. Messier noticed it on Aug. 3, 1764, next to M31.

M32 is one of the two small satellite galaxies of their more famous partner, M31. It is an elliptical dwarf galaxy with a diameter of only 8,000 light-years.
M32 and NGC205 are galaxies located nearby also.
Open star cluster NGC752 is visible without optics but becomes quite a bevy of stars with a telescope.
NGC891 can be seen as a spiral galaxy in a 4.5inch(112.5mm) telescope.
M32 is the smaller of the two, and is slightly below M31. This small round galaxy is also known as NGC 221. It is magnitude 8.2, and appears about 1/8 of a degree across, dwarfed by its larger companion.
M32 (NGC 221) is the brightest elliptical satellite of M31, although rather faint compared to the latter. This galaxy is located almost half a degree to the south of M31 and is best seen in large telescopes.

Hubble has also allowed astronomers to probe the fine details of the Virgo Cluster's most prominent object"the huge M87 galaxy (Figure 25.5)"and what they have found is again in excellent agreement with the idea that the ...
This is the companion galaxy, M32. Increasing magnification, you can see it is an egg-shaped cloud of light. Next, to locate the Triangulum Galaxy, find the Great Square high in the east.
The implied mass for the central object in M32 is of order 107 solar masses; because of the high rotation, this estimate is not strongly dependent on the unknown anisotropies.
Close examination of the inner region of Andromeda showed a smaller dust ring that is believed to have been caused by the interaction with M32 more than 200 million years ago.
The Andromeda Galaxy has two satellites: M110 (NGC 205) and M32. M110 is located one degree northwest of M31 and M32 can be found half a degree south of M31. Both are elliptical galaxies.
Based on current evidence, it appears that M32 underwent a close encounter with M31 in the past.

Our Local Group belongs to an even larger structure, a supercluster with the rich Virgo cluster of galaxies at its centre, about 70 million light years (about 21 Mpc) away.

It is a poor, irregular cluster with some 20 certain members: three spirals (the Galaxy, M31, and M33); four irregulars (LMC, SMC, IC 1613, and NGC 6822); and about 13 intermediate or dwarf ellipticals (NGC 147; NGC 185; NGC 205; M32; the Sculptor, ...
The galaxies which are gravitationally bound to the , including Fornax, the , M31 (Andromeda Galaxy), M32, M33, M101, Small Magellanic Cloud, and 9 dwarf spheroidal galaxies.
The three brightest stars of Andromeda form a broad arc south of the distinctive 'W' of Cassiopeia, and under a dark sky the elongated shape of M32 is just visible to the unaided eye. This is by far the best-known object in the field.
ELLIPTICAL GALAXY
An elliptical galaxy is a galaxy that has the shape of an ellipse. It is also called an "E" or "E-type" galaxy. M87 and M32 are elliptical galaxies.

Also visible are the satellite galaxies M32 and M110 / NGC205. Also visible is NGC7662, the Blue Snowball Nebula, a planetary nebula; C23 / NGC891, a galaxy; and numerous open clusters.

It is flanked by two dwarf elliptical companion galaxies (M32 and M110). It is part of the Local Group, a cluster of galaxies to which we (in the Milky Way) belong.
The Andromeda Galaxy can just be seen with the naked eye in the .
Its two brightest companion galaxies are M32 and M110. The light arriving at earth from the Andromeda Galaxy is shifted toward the blue end of the spectrum, whereas the light from all other cosmic sources exhibits red shift.
Several companion galaxies are also visible, including M32 - a dwarf elliptical directly below the central bulge and just outside the spiral arms - and M110 which is above and to the right of the center.
