202 Chryseïs is a large, lightly colouredMain beltasteroid that is probably composed ofsilicate rocks. It was discovered byC. H. F. Peters on September 11, 1879, inClinton, New York, and was named after the mythicalTrojan womanChryseis.
The rotation period for this asteroid is close to a day long, so the construction of a completelight curve requiresphotometric observations from multiple locations at widely spaced latitudes. This task was completed in January and February, 2011, yielding a synodicrotation period of 23.670 ± 0.001 h, with a brightness variation of 0.20 ± 0.02 inmagnitude[3]
