Moderate NGC 2682 Rating: 2 M Other Names: Melotte 94; Collinder 204; Raab 81, M67 Astronomical Leage Program: Messier Club,Urban Deep Sky Club Position: 0850+1149 Type: Oc Class: II 3r Magnitude: 6.9 Dimensions: 29' Cluster population: 500 Notes:

Messier cataloged it on April 6, 1780. It is 12 light years in diameter. Its H-R diagram is closer to a globular cluster than an open cluster, since the brighter

stars have already turned off the Main Sequence. (This turn-off point is at absolute magnitude +3.5. As clusters age, the leaving point for their stars moves down and to the right on the Main Sequence H-R diagram. That this leaving point is at such a dim magnitude suggests that the cluster has been around for an awful long time. In fact, the H-R diagram suggests an age of 10 billion years for M67! Recently, NGC 188 has been shown to have a similar spectral composition.) Perhaps one reason it has survived so long as an open cluster is that it lies high above the plane of the galaxy (1,500 light years or so).

The brightest star– a B9V– is 9m (about 50 times brighter than the Sun). This cluster is 5 times as far as the Beehive (M44), also located in Cancer, but is only

1/4 the diameter.
