The western edge of visible part of the Moon, and of Oceanus Procellarum. Observers with larger telescopes can have a look at the rilles on the floor of Hevelius and Rima Cardanus. Here we find a unique formation, one of a kind, Reiner Gamma.
Crater. (50Km /32Mi ø ) (Dept: 2,300m /7,000ft) (13.2°N, 72.4°W) Connected with Krafft through a rille. (See Chart 17)
Crater. (60Km /38Mi ø ) (Dept: 3,000m /9,100ft) (5.1° N, 66.8° W) Clearly pronounced crater. Flat floor with small central mountain. It nearly joins the northern rim of Hevelius to the south.
GALILAEI - Galilaei Galileo (1564 - 1642) Italian astronomer and mathematician, physicist, founder of modern natural sciences. Builder of a telescope with which he observe the Moon, Jupiter's Moons and the stars. He defended the theory of Copernicus.
HEVELIUS - Johannes Hevelius (1611 - 1687) Mayor of Danzig, astronomer, selenographer, founder of lunar topography. Described ten new constellations. Seven of which still carry the names he gave them.
Crater (74 Km /44Mi ø ) (Dept: 3,000m /9,100ft) (7.4°N 75.9°W) Remains of an eroded walled plain, supporting Olbers A to the North-West Olbers K to the West and Olbers B to the East. High walls. Flat floor filled with lava.
Crater floor (7.13°N, 64.37°W) Northeast of Cavalerius crater we find the site designated Planitia Descensus, the landing site of the Russian Luna 9 probe, the first vehicle to soft-land on the Moon. It lies among some low ridges along the edge of the Oceanus Procellarum.
1606 – 1647) Italian mathematician and astronomer. He was a friend and disciple of Galileo Galilei. Crater. (93Km /58Mi ø ) (Dept: 2,780m /9121ft) (13.9°N, 83.9°W) The northern and southern parts of the rim of Vasco da Gama have been heavily eroded by impacts, with the western and eastern rims being more intact.
