Biot is a small, bowl-shaped lunar impact crater located in the southern reaches of the Mare Fecunditatis. It is named after French astronomer Jean-Baptiste Biot."Biot (crater)". Gazetteer of Planetary Nomenclature. USGS Astrogeology Research Program. It is a circular formation with a sharp-edged rim that has not been significantly worn. The inner walls slope down to a relatively small interior floor. The albedo of the wide inner walls is higher than the surrounding lunar mare, giving it a light hue. To the southeast is the crater Wrottesley.
