381 Myrrha
381 Myrrha is a main-belt asteroid that was discovered by the French astronomer Auguste Charlois on January 10, 1894, in Nice.[3] It has been classified as a C-type asteroid and is most likely composed of carbonaceous material.
Photometric observations of this asteroid at the Oakley Observatory in Terre Haute, Indiana during 2006 gave a light curve with a period of 6.572 ± 0.002 hours and a brightness variation of 0.34 ± 0.05 in magnitude.[4]
10μ radiometric data collected from Kitt Peak in 1975 gave a diameter estimate of 126 km.[5] The occultation of Alhena (γ Geminorum) by Myrrha was observed in Japan and China on January 13, 1991, allowing the size and shape of Myrrha to be properly clarified.
