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.

(171) Офелия (лат. Ophelia) — довольно крупный астероид главного пояса, принадлежащий к тёмному спектральному классу C, состоящей, вероятно, из простейших углеродных соединений, схожих с хондритными метеоритами, найденными на Земле и входит в состав семейства Фемиды. Астероид был открыт 13 января 1877 года французским астрономом Альфонсом Борелли в Марсельской обсерватории и назван в честь Офелии, вымышленного персонажа трагедии Уильяма Шекспира «Гамлет».Другой контент может иметь иную лицензию.
