Tyagaraja is the third-largest crater of the Kuiperian system on Mercury, at 97 km diameter, after Bartók crater and Amaral crater.^[3]

Hollows are present within Tyagaraja. Within the extensive hollows of Tyagaraja is a dark spot of low reflectance material (LRM), closely associated with the central peak complex.^[4] Another prominent dark spot is located to the southwest of Tyagaraja, on the north rim of an unnamed crater.

An irregular depression is present within the central peak complex of the crater. This may be evidence of explosive volcanism.^[5]

The larger Phidias is to the north, and the crater Stevenson is to the east.
