It is large in size and its surface is dark. It has probably similar primitive composition as the carbonaceous chondrite meteorites.


It was discovered by Alphonse Borrelly on January 13, 1877 and named after the character in Shakespeare's Hamlet.


Discovery of a possible satellite was reported in 1979 based on lightcurve data. However, it has not been confirmed.


Ophelia is also the name of a moon of Uranus.
