179 Klytaemnestra is a fairly large main belt asteroid that was discovered by Canadian-American astronomer James Craig Watson on November 11, 1877.[3] It was the last of his 22 asteroid discoveries,[4] and was named after Clytemnestra, the wife of Agamemnon in Greek mythology. This is classified as a stony S-type asteroid, based upon its spectrum.
Photometric observations of this asteroid at the Oakley Observatory in Terre Haute, Indiana during 2006 gave a light curve with a period of 11.13 ± 0.02 hours and a brightness variation of 0.55 ± 0.02 in magnitude.[5]
