Messier 41 (also known as M41 or NGC 2287) is an open cluster in the constellation Canis Major. It is sometimes referred to as the Little Beehive Cluster . [ 4 ] It was discovered by Giovanni Batista Hodierna before 1654 and was perhaps known to Aristotle about 325 BC. [ 5 ]
The only Messier object is M41 (NGC 2287), an open cluster with a combined visual magnitude of 4.5, around 2300 light-years from Earth. Located 4 degrees south of Sirius, it contains contrasting blue, yellow and orange stars and covers an area the apparent size of the full moon —in reality around 25 light-years in diameter. [ 87 ]
The following is a list of NGC objects, that is objects listed in the New General Catalogue (NGC). It is one of the largest comprehensive astronomical catalogues for deep sky objects such as star clusters, nebulae, and galaxies.

Méchain later concluded that this object was simply a re-observation of M101, though some sources suggest that the object Méchain observed was the galaxy NGC 5866 and identify that as M102. [ 12 ] Messier's final catalogue was included in the Connaissance des Temps pour l'Année 1784 [ Knowledge of the Times for the Year 1784 ], the French ...
NGC 2207 and IC 2163 are a pair of colliding spiral galaxies about 80 million light-years away [2] in the constellation Canis Major. NGC 2207 was discovered by British astronomer John Herschel on 24 January 1835, [3] while IC 2163 was discovered by Herbert Howe on 11 February 1898.

NGC 2283 is a barred spiral galaxy in the constellation of Canis Major. Its velocity with respect to the cosmic microwave background is 994 ± 11 km/s, which corresponds to a Hubble distance of 14.66 ± 1.04 Mpc (∼48 million light-years ). [ 1 ]
Messier 81 (also known as NGC 3031 or Bode's Galaxy) is a grand design spiral galaxy about 12 million light-years away in the constellation Ursa Major. It has a D 25 isophotal diameter of 29.44 kiloparsecs (96,000 light-years ).
NGC 2257 is a globular cluster that lies on the outskirts of the Large Magellanic Cloud (LMC). It was discovered in 1834 by John Herschel.The compiler of the New General Catalogue, John Louis Emil Dreyer, described this cluster as "faint, considerably large, round, very gradually a little brighter middle, mottled but not resolved, 17.0 seconds of time diameter."
