40 Harmonia
Lua error in Module:Infobox at line 314: malformed pattern (missing ']'). 40 Harmonia /hɑːrˈmoʊniə/ is a large main-belt asteroid. It was discovered by German-French astronomer Hermann Goldschmidt on March 31, 1856,[4] and named after Harmonia, the Greek goddess of harmony. The name was chosen to mark the end of the Crimean War.
The spectrum of 40 Harmonia matches an S-type in the Tholen classification system, and is similar to primitive achondrite meteorites.[5]
Photometric observations at the Organ Mesa Observatory in Las Cruces, New Mexico during 2008–09 were used to generate a light curve that showed four unequal minima and maxima per cycle. The curve shows a period of 8.909 ± 0.001 hours with a brightness variation of 0.28 ± 0.02 in magnitude. This result is compatible with previous studies.[2]
Speckle interferometric observations carried out with the Nicholas U. Mayall Telescope at the Kitt Peak National Observatory during 1982–84 failed to discover a satellite companion.[6] In 1988 a search for satellites or dust orbiting this asteroid was performed using the UH88 telescope at the Mauna Kea Observatories, but the effort came up empty.[7]
