Telescope: Astro-Physics 160 EDF | Description:Messier 41 (also known as M41 or NGC 2287) is an open cluster in the constellation Canis Major. It was discovered by Giovanni Batista Hodierna. It lies about four degrees almost exactly south of Sirius, with which it forms a roughly equilateral triangle with Nu2 Canis Majoris to the west. The cluster fits into the size of the full moon. It contains about 100 stars, including several red giants the brightest of which has spectral type K3, apparent magnitude 6.3 and is near the center. The diameter of the cluster is 25–26 light-years. It is estimated to be 190 million years old, and cluster properties and dynamics suggest a total life expectancy of 500 million years for this cluster, before it will have disintegrated. (Wiki). |
