Peary is the closest large lunar impact crater to the lunar north pole. At this latitude the crater interior receives little sunlight, and portions of the southernmost region of the crater floor remain permanently cloaked in shadow. From the Earth the crater appears on the northern lunar limb, and is seen from the side.
Observation and Etymology
Since Peary is located nearly on the limb of the Moon as viewed from Earth, high-quality images of the crater were not available until space probes started photographing the Moon; the first high-quality images came from the US
Physical features
Peary is nearly circular, with an outward bulge along the northeast rim. There is a gap in the southwestern rim, where it joins the slightly smaller crater
Because of the low sun angle, the average temperature on the crater floor or Peary is between 30 and 40 K, one of the coldest locations in the Solar System.[3]
Illumination
In 2004, a team led by Dr
The northern rim of Peary is considered a likely site for a future
