Ophelia (minor planet designation : 171 Ophelia ) is a large, dark Themistian asteroid [5] that was discovered by French astronomer Alphonse Borrelly on 13 January 1877, and named after Ophelia in Shakespeare 's Hamlet .[6]
This asteroid is a member of the Themis family of asteroids that share similar orbital elements .[7] It probably has a primitive composition, similar to that of the carbonaceous chondrite meteorites .
A 1979 study of the Algol -like light curve produced by this asteroid concluded that it was possible to model the brightness variation by assuming a binary system with a circular orbit, a period of 13.146 hours, and an inclination of 15° to the line of sight from the Earth.[8] Photometric observations of this asteroid at the Leura Observatory in Leura , Australia during 2006 gave a rotation period of 6.6666 ± 0.0002 hours and a brightness variation of 0.50 ± 0.02 in magnitude . This is in agreement with previous studies.[9]
Ophelia is also the name of a moon of Uranus .
