M41 Open Star Cluster in Canis Major. This large bright Open star cluster can be found about 4 degrees South of 'Sirius'- Alpha Canis Majoris (The brightest star in the sky). The cluster in our night sky 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 centre, and some white dwarfs. The cluster is estimated to be moving away from us at 23.3 km/s. The diameter of the cluster is 25-26 light-years (7.7-8.0 pc). It is estimated to be 190 million years old. | |
