Chryseïs (minor planet designation: 202 Chryseïs) is a large, lightly coloured Main belt asteroid that is probably composed of silicate rocks. It was discovered by C. H. F. Peters on September 11, 1879, in Clinton, New York, and was named after the mythical Trojan woman Chryseis.

The rotation period for this asteroid is close to a day long, so the construction of a complete light curve requires photometric observations from multiple locations at widely spaced latitudes. This task was completed in January and February, 2011, yielding a synodic rotation period of 23.670 ± 0.001 h, with a brightness variation of 0.20 ± 0.02 in magnitude[3]

(202) Хрисеида (др.-греч. Χρυσηίς) — довольно крупный астероид главного пояса, принадлежащий к силикатным астероидам светлого спектрального класса S. Он был открыт 11 сентября 1879 года германо-американским астрономом К. Г. Ф. Петерсом в обсерватории Клинтона, США и назван в честь Хрисеиды, героини поэмы Гомера «Одиссея», дочери Аполлона[1].Другой контент может иметь иную лицензию.
