Eponym François F. Tisserand

Tisserand is a lunar crater that is located just to the east of the larger crater Macrobius, to the northwest of the Mare Crisium. East is a wrinkly ridge known as Dorsum Oppel.

The crater is named after Félix Tisserand.[1]

The rim of Tisserand has been eroded by impacts, with depressions in the southern and northeastern sides, and a nearly tangential curving valley cutting into the inner wall along the northwest. The interior floor is relatively level, with low ridges near the eastern and western inner walls. The eastern half of the floor has a slightly lower albedo than the western half, with the latter part being lightly coated by ray material from Proclus to the south.

From that location the Earth would appear in the lunar sky at 69 degrees above the horizon towards the south, in the east, it is seen more than 48 degrees towards the east.

Satellite craters[edit]

By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Tisserand. Tisserand A is nearly to the southeast, east of that is Tisserand B, Tisserand D is about 15 km east-northeast and Tisserand K is nearly further southeast.
