on Wednesday, February 12, 2020
Messier 46 (M46) is an open cluster that can be found in the constellation Puppis, to the upper left of the star Sirius in Canis Major. The cluster is fairly bright and contains about 500 stars and is about 5,400 light years away. If you close you can also spot the planetary nebula, a small ring, known as NGC 2437, while it looks like it is part of the cluster, it is actually in front of it by 2,500 light years.
