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 ]
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 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 ]
The Beehive Cluster (also known as Praesepe (Latin for "manger", "cot" or "crib"), M44, NGC 2632, or Cr 189), is an open cluster in the constellation Cancer. One of the nearest open clusters to Earth , it contains a larger population of stars than other nearby bright open clusters holding around 1,000 stars .

Messier 34 (also known as M34, NGC 1039, or the Spiral Cluster) is a large and relatively near open cluster in Perseus. It was probably discovered by Giovanni Batista Hodierna before 1654 [ 4 ] and included by Charles Messier in his catalog of comet -like objects in 1764.
Cetus A, M77, NGC 1068, 3C 71, 4C-00.13, Arp 37, UGC 2188, PGC 10266 [7] Messier 77 ( M77 ), also known as NGC 1068 or the Squid Galaxy , is a barred spiral galaxy in the constellation Cetus . It is about 47 million light-years (14 Mpc ) away from Earth, and was discovered by Pierre Méchain in 1780, who originally described it as a nebula.
