M93 is one of the smaller but bright open clusters, the stars forming a triangular shape, while Kenneth Glyn Jones found it more like a butterfly, and Admiral Smyth was reminded to a star-fish. At least about 80 members appear scattered over its 22' apparent diameter, which is of the order of 20-25 light years linearly at its distance of about 3,600 light years.
The brightest stars of M93 are blue giants of type B9, its age has been
estimated as roughly 100 million years. Its Trumpler classification is
given as I,3,r.
