Image Mission Elapsed Time (MET):
Narrow Angle Camera (NAC) of the Mercury Dual Imaging System (MDIS)
550 meters (0.34 miles) per pixel
Oskison is 120 kilometers (75 miles) in diameter
21,700 kilometers (13,500 miles)
The crater Oskison is located in the far northern hemisphere of Mercury, in the plains north of Caloris basin
. Oskison is a distinctive crater with a large central peak that exposes material excavated from depth. In this NAC image, many chains of secondary craters
are visible (green arrows), radiating from Oskison outward onto the surrounding smooth plains. Oskison was just named
in November 2008 for John Milton Oskison, a Cherokee author (1874-1947).
