Description of object:
M 11 is a compact open cluster in the constellation Scutum (the
Shield). It contains some 2900 stars in a distance of 6300 lightyears. D The
diameter of the bright inner part of the cluster is about 10 arcminutes,
corresponding to an absolute diameter of 18 lightyears. The distribution if
main sequence stars shows that the whole cluster is about three times bigger in
diameter, approximately as large as the Moon in the sky. The Age of M 11 is
about 250 million years, so it is an "intermediate age" cluster.
