LO-IV-160H Biot is at the bottom. The 8-km diameter crater above it is Biot C.

High albedo crater Biot was photographed by the orbital Mapping/Metric Fairchild camera of Apollo 15. Biot was captured on several oblique south looking frames, of which frame AS15-M-2531 shows Biot's appearance as a bright "streak" near the central part of the curved horizon.

(IAU Directions) BIOT.--A brilliant little ring-plain, scarcely more than 7 miles in diameter, standing in an isolated position in the Mare Fecunditatis N.W. of Wrottesley. There is a number of bright streaks in its neighbourhood; and a few miles W. of it, in the hilly region E. of Santbech, another conspicuous crater of about the same size.
- Depth data from Kurt Fisher database
- Westfall, 2000: 0.9 km
- Viscardy, 1985: 1.5 km
- From the shadows in LO-IV-160H the depth of Biot is about 2800 m. Biot C is about 1300 m deep. - Jim Mosher
- Included in ALPO list of bright ray craters
- Biot and its satellite crater A are on the ALPO list of banded craters
L.F.Ball's straight rille
- Harold Hill, in his wonderful book A Portfolio of Lunar Drawings, describes earlier observations by L.F.Ball, R.Barker, and H.P.Wilkins, of an alleged straight rille running from the southern part of Biot's rim to the ridges southward of Wrottesley. Something which he (H.Hill) was unable to confirm.
- Named for Jean-Baptiste Biot (1774-1862), a French astronomer.
- According to Gunther P. Konnen (Polarized Light in Nature), Biot seems to have been the first one who discovered the polarization of the rainbow (around 1811). - DannyCaes Apr 20, 2014
- Biot is Catalog number 4396 in the Collated List and the original IAU nomenclature of Named Lunar Formations. The name is said to have originated in Beer and Mädler.
- Biot Beta (the pronounced mountain-like mass east-northeast of Biot, northwest of Wrottesley) (see Chart 87 in the Times Atlas of the Moon).
- This rather pronounced island (Biot Beta) seems to have been unknown (?) during the making of SLC map A6 (System of Lunar Craters, 1966).
