Consequently, it is never visible with binoculars, having a maximum apparent magnitude at the best possible opposition of around +10.2 (as in November 2011), which is fainter than any of the thirty asteroids previously discovered.

During perihelic oppositions, Euphrosyne is very high in the sky from northern latitudes and invisible from southern countries such as New Zealand and Chile.

Euphrosyne is a C-type asteroid with a primitive surface possibly covered by thick ejecta blanket from the collision that created its moon and collisional family.

Any craters larger than 40 km in diameter must have flat floors to not be visible in the VLT images, consistent with an icy C-type composition.

[4] Euphrosyne is the namesake of a complex family of about two thousand asteroids that share similar spectral properties and orbital elements.
