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, and is a C-type asteroid, which means that it is dark in colouring with a carbonate composition. Its density appears to be unusually low, indicating that it may be a loosely-packed rubble pile, not a monolithic object.
In 2000, astronomers at the Canada-France-Hawaii Telescope on Mauna Kea, Hawaii, discovered a small, 15 km moon orbiting Pulcova at a distance of 800 km. It was one of the first asteroid moons to be identified.
