Daniell is a lunar impact crater located in the southern half of the Lacus Somniorum.

The rim of Daniell is oval in form, with the long axis oriented north-northwest to south-southeast.

[1] Lunar geologist Chuck Wood speculated that the fractured floor may have been uplifted by the massive slumps on northwest and southeast rims.

[2] The crater was named in 1935 by the IAU after British physicist, chemist, meteorologist John F.

[3] By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Daniell.
