NGC 6642
NGC 6642 is a globular cluster located 26,700 light-years from Earth, in the constellation Sagittarius. Many "blue stragglers" have been spotted in this globular, and it is known to be lacking in low-mass stars.
During the June 2094 lunar eclipse, a total lunar eclipse, it will be occulted by the Moon over New Guinea, Northern Australia and the Pacific Ocean.
