Unlike other Mercurian craters of similar size, Raphael is not multi-ringed.[3]

The crater Flaiano lies just south of the center of Raphael.

There is also a high-albedo area east of Flaiano, that is associated with irregular depressions. The area was named Madu Facula by the IAU in 2023.[4] The depressions are similar to those within Navoi, Lermontov, Scarlatti, and Praxiteles. The depressions resemble those associated with volcanic explosions.[5]
