Description

Caroline's Rose Cluster, NGC 7789 is an open cluster in Cassiopeia, discovered by Caroline Herschel in 1783. Found among the rich star fields of the Milky Way, star cluster NGC 7789 lies about 8,000 light-years away, with stars that all formed at the same time, approximately 1.6 billion years ago.

Over 50 light-years across, Caroline's Rose spans about half a degree, the size of a full moon. Shining at magnitude 6.7, it is just beyond the ability of the naked eye, but is a beautiful object in binoculars or a small telescope.
