Messier   3   (also   known   as   M3   or   NGC   5272)   is   a globular     cluster     of     stars     in     the     northern constellation   of   Canes   Venatici.   It   was   discovered by Charles Messier on May 3, 1764. Many   amateur   astronomers   consider   it   one   of the   finest   northern   globular   clusters,   following only Messier 13. This   cluster   is   one   of   the   largest   and   brightest, and    is    made    up    of    around    500,000    stars.    It    is estimated   to   be   8   billion   years   old.   It   is   located at   a   distance   of   about   33,900   light-years   away from Earth.
