Eponym	John F. Daniell

Daniell is a lunar impact crater located in the southern half of the Lacus Somniorum. To the south-southeast is the much larger crater Posidonius. Nearby can be found the Rimae Daniell rille system.

The rim of Daniell is oval in form, with the long axis oriented north-northwest to south-southeast. Most of the wall is well-formed and relatively free of wear, although it appears slumped at the southern end. The interior is relatively featureless, and lacks a central peak. The floor surface has a lower albedo than the surroundings and has some cleft-like features.

Satellite craters

By convention these features are identified on lunar maps by placing the letter on the side of the crater mid-point that is closest to Daniell.
