NGC 6687 is an open star cluster located in the constellation Scorpius. It was discovered by the astronomer John Herschel in 1834. This cluster is approximately 3,500 light-years away from Earth and contains several hundred stars, which are relatively young and hot. The stars in NGC 6687 are bound together by gravity and share a common origin. Open clusters like this one are important for studying stellar evolution and the dynamics of star formation. Observations of NGC 6687 can provide insights into the life cycles of stars and the conditions in which they form.
