Excerpt: Peary is the closest large lunar impact crater to the lunar north pole. At this latitude the crater interior receives little sunlight, and parts of the southern floor remain permanently cloaked in shadow. From the Earth the crater appears on the northern lunar limb, and is seen from the side. The crater is nearly circular, with an outward bulge along the northeast rim. There is a gap in the southwestern rim, where it joins a slightly smaller worn crater formation. The outer rim of Peary is worn and eroded, creating a rugged mountainous ring that produces long shadows across the crater floor. The crater floor is relatively flat, but marked by several small craterlets, particularly in the eastern half. The southern third of the interior remains cloaked in shadows, and so its features cannot be readily discerned. The worn and lava-flooded crater Byrd lies close to the southern rim of Peary. To the northwest, about a quarter the way around the lunar pole, is the larger crater Hermite. On the opposite side of the pole, on the far side of the Moon, lies the still-larger Rozhdestvenskiy. In 2004, a team led by Dr. Ben Bussey of Johns Hopkins University using images taken by the Clementine mission determined that four mountainous regions on the rim of Peary...
