M71 Observation Details
M71 Daily Motion
M71 will be visible until December, 30, when it will move too close to the Sun. During this time, its proximity to the Sun will cause it to disappear from the night sky, making it unobservable for a while.

M71 - Globular Cluster
M71 is a globular cluster located in the constellation Sagitta. It was discovered by Philippe Loys de Chéseaux in 1745 and later cataloged by Charles Messier in 1780. The cluster is relatively loose for a globular cluster.
M71 spans about 27 light-years across and contains around 10,000 stars. The cluster is approximately 13,000 light-years away from Earth and has an apparent magnitude of 8.2, making it visible with binoculars or a small telescope.
