Globular cluster in Coma Berenices

|
Discovered 1775 by Johann Elert Bode, M53 is one of the more outlying globulars, being about 60,000 light years away from the Galactic center,
and almost the same distance (about 58,000 light years) from our Solar system. M53 has a bright compact central nucleus of about 2' in diameter, although its stars are not very concentrated toward the center when compared to other globulars, and a gradually decreasing density profile to the outer edges.
