Messier 47 is an open cluster that can be found one degree West of M46, but M47 is not as rich in stars (about 50 stars, one tenth of M46), is younger (78 million years old) and lies much closer to us (1600 light years). The brightest star in the cluster (HD 60855) is a B2Ve C-Type star, located near the bottom of the image. The cluster also contains two red giants (on the right side of the image), HD 61114 and HD 60898, both about 200 times more luminous than our Sun.
