Tisserand (crater)
Template:Infobox Lunar crater Tisserand is a lunar impact crater located just to the east of the larger crater Macrobius, to the northwest of the Mare Crisium. The crater was named after French astronomer François Félix Tisserand in 1935.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>
The rim of Tisserand has been eroded by impacts, with depressions on the southern and northeastern sides and a winding 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.
Tisserand is a crater of Nectarian age.<ref>The geologic history of the Moon. USGS Professional Paper 1348. By Don E. Wilhelms, John F. McCauley, and Newell J. Trask. U.S. Government Printing Office, Washington: 1987. Table 9-4.</ref>
