Hipparchus is the degraded remnant of a
lunar crater. It is located to the southeast of
Sinus Medii, near the center of the visible
Moon. To the south is the prominent crater
Albategnius, and to the southwest lies
Ptolemaeus, a feature of comparable dimensions to Hipparchus.
Horrocks lies entirely within the northeast rim of the crater.
Halley is attached to the south rim, and
Hind lies to the southeast. To the north-northeast is the bowl-shaped
Pickering, and the flooded
Saunder is located off the northeast rim.
