The low rim of this formation is heavily eroded and overlaid by multiple smaller craters. The most notable of these is Fleming along the southern rim, while another, only slightly smaller crater cuts across the lower eastern rim. The interior floor is also marked by a number of small impacts and a few ghost-crater rims.

The crater was named after Alexander and Williamina Fleming. Prior to naming in 1970 by the IAU,^[1] this crater was known as Crater 203.^[2]

Fleming is one of the largest craters of Nectarian age.^[3]
