 | | Its denser, easily visible core is only about 5 to 6 arc minutes, while in photos it has an angular diameter of about 7', corresponding to a linear extension of only 25 light years, small for a globular cluster. |
 | | M71 was first seen by De Cheseaux who cataloged it as his No. 13, and later rediscovered by Johann Gottfried Koehler between 1772 and 1779, and by Pierre Mechain on June 28, 1780. |
 | | Charles Messier cataloged it based on his observations of October 4, 1780, as a nebula without stars. |
