NGC 2244 is the tidy little star cluster born out of the Rosette Nebula some many millions of years ago. It's about 5000 light years away.

The cluster is found 2.5º due south of 13 Monocerotis, in the lower left portion of the Rosette Nebula.

The bright yellow giant 12 Monocerotis seems to be at its centre, but in fact this star is much closer (520 light years).
