762 Pulcova
762 Pulcova is a main-belt asteroid. It was discovered by Grigoriy N. Neujmin in 1913,〔 and is named after Pulkovo Observatory, near Saint Petersburg. Pulcova is 137 km in diameter,〔(【引用サイトリンク】title=JPL Small-Body Database Browser: 762 Pulcova (1913 SQ) )〕 and is a C-type asteroid, which means that it is dark in colouring with a carbonate composition. Photometric observations of this asteroid from Leura, Australia during 2006 gave a light curve with a period of 5.8403 ± 0.0005 hours and a brightness variation of 0.20 ± 0.02 in magnitude. This result is in agreement with previous studies.〔 == Satellite == On February 22, 2000,〔 (AO image)〕 astronomers at the Canada-France-Hawaii Telescope on Mauna Kea, Hawaii, discovered a small, 15-km moon (roughly a 10th the size of the primary)〔 (mentions both 90 Antiope and 762 Pulcova)〕 orbiting Pulcova at a distance of 800 km.〔 Its orbital period is 4 days. The satellite is about 4 magnitudes fainter than the primary.〔 It was one of the first asteroid moons to be identified.
