J. Herschel (crater)
J. Herschel is large
lunar crater of the variety termed a walled-plain. It is located in the northern part of the
Moon's surface, and so appears foreshortened when viewed from the
Earth. The southeastern rim of J. Hershel forms part of the edge of the
Mare Frigoris lunar mare. To the northwest is
Anaximander crater. Bordering the northern rim is a large, unnamed lunar plain. Just to the south is the small
Horrebow crater.
The rim of this crater has been heavily eroded, to the point where it is frequently described as "considerably disintegrated". The remaining rim survives as a ring of ridges that have been resculpted by subsequent impacts. The interior floor is relatively level, but irregular and marked by a multitude of tiny impacts. The most notable of these are the satellite craters C, D, K, and L, listed in the table below. 'Horrebow A' is attached to the southern rim of the crater, and is overlapped along its southwest rim by Horrebow.
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 J. Herschel crater.
