L28 - Hipparchus

Hipparchus Crater is 91 miles in diameter. It is an older crater with some craterlets within it. The largest crater within its rim is Horrocks. There is also part of a faint 'ghost' crater on Hipparchus' floor. Hipparchus also has historical significance being the subject of the first known sketch of a single lunar feature, done by Robert Hooke in 1665.
