This is the largest crater on the near side of the Moon.
In area it is comparable in size to a small mare.
It lies north of the crater Le Gentil and east of Hausen.
Further west of Bailly are the (unofficially named) Montes Dörfel mountains.

Bailly's uneven crater floor has remained free of lava flooding, and it is covered with a multitude of ridges and craters.
The entire crater has been battered and worn, and the outer ramparts are eroded and in some places have even been worn away by myriad impacts.
If the crater ever possessed a central peak, it is no longer discernible.
Due to its current condition, observers have termed this feature a 'field of ruins'.
