Epimetheus is an inner satellite of Saturn. It is also known as Saturn XI. It is named after the mythological Epimetheus, brother of Prometheus.
Pallene is a very small natural satellite of Saturn. It is one of three small moons known as the Alkyonides that lie between the orbits of the larger Mimas and Enceladus. It is also designated Saturn XXXIII.
Ångström is a small lunar impact crater located on the border between Oceanus Procellarum to the west and Mare Imbrium to the east. To the south is a formation of mountains rising out of the mare named the Montes Harbinger. To the east are some wrinkle ridges named the Dorsum Bucher and Dorsa Argand. This crater is bowl-shaped, with a circular rim and inner walls that slope down to the small central floor. It has a higher albedo than the surrounding maria. The crater halo is radar dark, indicating a lack of larger blocks among the fine ejecta.
A wrinkle ridge is a type of feature commonly found on lunar maria, or basalt plains. These features are low, sinuous ridges formed on the mare surface that can extend for up to several hundred kilometers. Wrinkle ridges are tectonic features created after the lava cooled and solidified. They frequently outline ring structures buried within the mare, follow circular patterns outlining the mare, or intersect protruding peaks. They are sometimes called veins due to their resemblance to the veins that protrude from beneath the skin.
Aratus is a small lunar impact crater located on the highland to the south and east of the rugged Montes Apenninus range. It is a circular, cup-shaped crater with a relatively high albedo. It was named after Greek astronomer Aratus of Soli. To the east is the Mare Serenitatis, and to the southwest is the somewhat larger crater Conon. North-northeast of Aratus is the landing site of the Apollo 15 mission, just beyond Mons Hadley Delta.
Mons La Hire is a solitary lunar mountain in the western Mare Imbrium. It is located to the northeast of the crater Euler, and to the west-northwest of Lambert.
Dorsum Buckland is a large wrinkle ridge at 20.4°N 12.8°E in Mare Serenitatis on the Moon, 369 km long. It was named after British geologist William Buckland in 1976.
Dorsum Heim is a wrinkle ridge at 32.0°N 29.8°W in Mare Imbrium on the Moon. It is 148 km long and was named after Swiss geologist Albert Heim in 1976.
Dorsum Bucher is a wrinkle ridge at 31.0°N 39.0°W in the border region between Oceanus Procellarum and Mare Imbrium on the Moon. The name of the feature was approved by the IAU in 1976. It is approximately 85 km long, extending from the vicinity of Gruithuisen crater to the area west of Delisle crater. The south end of the dorsum is a low hill of terra material that predates the mare lava.
