Borda is a lunar impact crater that lies between Santbech to the north-northwest and Reichenbach slightly further away to the south-southeast. It has a low rim that is broken along the southeast by a smaller crater. The rim is intruded into by another small crater along the southwest side, and there is an irregular cleft along the northwest face. There is a central peak at the midpoint of the floor. Vallis Snellius extends eastward from south of this crater to Hase D, a length of 500 km.
This crater is named after French astronomer Jean-Charles de Borda (1733-1799). His name was incorporated into lunar nomenclature by German astronomer J. H. von Mädler in 1837. Its designation was formally adopted by the International Astronomical Union in 1935.
Satellite craters By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Borda.
