	762 Pulcova
		Pulcova is 137km 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, 15km moon orbiting Pulcova at a distance of 800km.

		Asteroid Pulcova was observed in February 2000 at the 3.6 m Canada-France-Hawaii Telescope, located atop Mauna Kea on the Big Island of Hawaii.
		Asteroid Pulcova itself has a diameter of 150 km, and the moonlet orbits Pulcova at a distance of 800 km.
		The measurements made on Pulcova confirm that it, like Eugenia, is a low density object, with a density just barely greater than water.

		In another dazzling example of cosmic paparazzi, made possible with the latest in ground-based telescope technology, Asteroid 762 Pulcova has been spotted with a wee little companion, becoming only the third known asteroid to have what scientists call a moonlet.
		With the Pulcova pairing, the smaller moonlet is only about one-tenth the size of the 90-mile- (145-kilometer-) wide main rock.
		Pulcova and its moon were photographed by the Canada-France-Hawaii Telescope (CFHT), also on Mauna Kea.

		On 2005 Feb 06 UT, the 137 km diameter asteroid (762) Pulcova will occult a 11.7 mag star in the constellation Auriga for observers along a path across Alaska, Australia.
		In the case of an occultation, the combined light of the asteroid and the star will drop by 1.7 mag to 13.2 mag (the magnitude of the asteroid) for at most 21.2 seconds.

	binary asteroid
		An asteroid that consists of two roughly equal parts that revolve around each other at close range.
		Several examples are known including (90) Antiope and (762) Pulcova.
		One way to explain such twinning is in terms of impacts that reduced the ancestral body to a collection of rubble.

	The Cosmic Mirror # 206
		(762) Pulcova has a companion about 4 magnitudes dimmer, according to observations with the 3.6-m CFHT: A moonlet of about 20 km orbits the 140-km wide parent every four days at a distance of 800 km.
		Until these discoveries only two asteroid moons had been spotted directly: Ida's moon Dactyl was a discovery by the Galileo spacecraft, and Eugenia's moon Petite-Prince was an earlier success by the CFHT Adaptive Optics system (see Updates # 124 story 2 and 150 story 3 sidebar 2).
		The new 1.8-meter telescope in Arizona (see Update # 8) has started operations in Sept. and should be able to catch NEAs 2.5-times fainter than the trusted 90-cm scope: UA Press Release, SpaceViews, Discovery.

		The satellite is about 4 mag fainter than the primary and our fit to the orbit indicates that it was inclined approximately 60\thinspace deg to the line-of-sight, with a semi-major axis of 800\thinspace km (0.6\arcsec) and a period of 4.0 days.

	April 2001 SJAA Ephemeris
		Asteroid 243 Ida, orbiting in the asteroid belt between Mars and Jupiter, was the first asteroid found to have a moon, which has been named Dactyl.
		At least three other asteroids, 3671 Dionysius, 45 Eugenia, and 762 Pulcova, have since been found to have moons.
		The brightest of these, Eugenia, runs about magnitude 11.9, itself an easy target for a medium sized telescope; give yourself a real challenge and try to see Eugenia's moon.

		We discovered both of these moons using ground-based adaptive optics --- Eugenia in 1998, but Pulcova only in the last year.
		Our fits to the orbits yield a surprisingly low density for Eugenia of 1.2 g cm^-3, but that of Pulcova is 50 F-type spectra are similar to the common C-types, but differ by the lack of a UV-band or UV-dropoff and by subtle, but measurable differences in the spectral slope.
		Both the UV-region and the existence of subtle absorption features in the near-IR (~ 9000 Angstrom) are diagnostic of the specific differences between F-, C-, and (Bus') X-class.
