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 ...
The Andromeda–Milky Way collision is a galactic collision predicted to occur in about 4.5 billion years between the two largest galaxies in the Local Group —the Milky Way (which contains the Solar System and Earth) and the Andromeda Galaxy. [1][2][3][4][5] The stars involved are sufficiently far apart that it is improbable that any of them ...
The Andromeda Galaxy (M31) has satellite galaxies just like the Milky Way. Orbiting M31 are at least 13 dwarf galaxies: the brightest and largest is M110, which can be seen with a basic telescope. The second-brightest and closest one to M31 is M32. The other galaxies are fainter, and were mostly discovered starting from the 1970s.
SA0 − [2] Size. 166,900 ly (51,160 pc) [2] Apparent size (V) 2.2 ′ × 2.002 ′ [2] Other designations. UGC 203, MCG +04-02-004, PGC 1351 [4] NGC 80 is a lenticular galaxy located in the constellation Andromeda. It is currently interacting with two other barred spiral galaxies NGC 47 and NGC 68, and was discovered on August 17, 1828 by John ...
NGC 753 is a spiral galaxy [3] located 220 million light-years away [2] in the constellation Andromeda.The galaxy was discovered by astronomer by Heinrich d'Arrest on September 16, 1865 [4] and is a member of Abell 262.
NGC 67. NGC 67 is an elliptical galaxy located in the constellation Andromeda that was discovered on October 7, 1855, by R. J. Mitchell, who described it as "extremely faint, very small, round". The galaxy belongs to the NGC 68 group, which also contains the galaxies NGC 68, NGC 69, NGC 70, NGC 71, NGC 72, and possibly NGC 74.
Nu Andromedae ( Nu And, ν Andromedae, ν And) is a binary star in the constellation Andromeda. The system has an apparent visual magnitude of 4.5, [ 2] which is bright enough to be seen with the naked eye. It is approximately 620 light-years (190 parsecs) from Earth. [ 1] Situated just over a degree to the west of this star is the Andromeda ...
NGC 7662 is a popular planetary nebula for casual observers. A small telescope will reveal a star-like object with slight nebulosity. A 6" telescope with a magnification around 100x will reveal a slightly bluish disk, while telescopes with a primary mirror at least 16" in diameter may reveal slight color and brightness variations in the interior.
