		Physical model for 1580 Betulia has been obtained by Drummond and Wisniewski (1990) on the basis of the 1976 apparition lightcurves.
		As new lightcurves of Betulia has just been released (Wisniewski et al., submitted to Icarus), they are used to redo the previous model of this asteroid.

	[7.05] Peculiar Betulia Re-visited: A Near-Earth Asteroid with a Bare-Rock Surface? (Site not responding. Last check: 2007-09-17)
		The small C-type asteroid (1580) Betulia is an unusual near-Earth object (NEO) with a lightcurve that changes dramatically with changing solar phase angle, presumably due to a highly irregular shape and/or unusual topographic features.
		Knowledge of the thermal properties of NEOs is crucial for meaningful calculations of the Yarkovsky effect, which is invoked to explain the delivery of collisional fragments from the main belt into near-Earth orbits, and apparently has a significant influence on the orbital evolution of potentially hazardous NEOs.
		We observed Betulia in June 2002 with the 3-m NASA Infrared Telescope Facility.

		1580 Betulia is a near-Earth asteroid which is notable for its triple-peaked optical lightcurve: It can exhibit three pairs of brightness minima and maxima per rotation, unlike most asteroids which exhibit only two.
		I will present an analysis of the 2002 Arecibo radar experiment on Betulia, showing how delay-Doppler images, continuous-wave Doppler spectra, and lightcurve data can be synthesized to determine the target's shape and spin state.
		They also provide an estimate of the asteroid's size, enabling us to address discrepancies in past analyses as to whether Betulia is a small object with a lunar-like fine-grained regolith or else a larger object with only large rocks or bare bedrock at its surface.

		The first observations I got at Dyer were of moving targets, which taught me a lesson.
		Here's a light curve of the Earth-approaching asteroid 1580 Betulia, taken when it approached to about 0.13 AU from us in May 1976.
		The apparent motion was fast enough to limit how long it spent in the photometer's aperture, since there was no declination drive available (this, a grazing occultation of Saturn, and Comet Hyakutake are the only times I can recall actually seeing orbital motion of natural objects).

		A very close approach within 0.077 AU of 5604 1992 FE, and moderately close approaches of planets 1580 Betulia and 6455 1992 HE are especially noteworthy.
		Observers are encouraged to give special attention to those which lie near the limit of their equipment.
		Planet 1580 Betulia makes 4 revolutions every 13 years, and continues in 2002 the series of close approaches of 1950, 1963, 1976, and 1989.

		Judith is the Jewish heroine whose story is narrated in the book of the Bible that carries her name.
		The city is Betulia, which is under the attack of the general Nabucodonosor Oloferne.
		Judith, a widow of great beauty, was convinced that God would save her people because they were innocent and without sin.

		At absolute magnitude 16 (4 and 2 km), the estimated completeness is only 15 percent, while at absolute magnitude 17.7 (2 and 1 km), it is only about 7 percent.
		The largest ECAs are 1627 Ivar and 1580 Betulia, each with diameter of about 8 km, or slightly smaller than the object whose impact ended the Cretaceous period.
		The smallest ECAs yet discovered are 1991 BA, an object that passed within 0.0011 AU (one-half the distance to the Moon) in January 1991, and 1991 TU, which passed within 0.0049 AU in October 1991; both have diameters of about 10 m.

	Asteroid Inroduction
		Some asteroids, such as 1 Ceres, 2 Pallas, and 4 Vesta, are nearly spherical, whereas others, like 15 Eunomia, 107 Camilla, and 511 Davida, are quite elongated.
		Still others, as, for example, 624 Hektor, 1580 Betulia, and 4769 Castalia (which appears in radar observations by the American astronomer Steven J. Ostro to resolve as two spheres in contact), apparently have bizarre shapes.
		The most widely used technique for determining the sizes of asteroids is that of thermal radiometry.

	NYU ELJ ARTICLE (1997)
		Only a small fraction of near-Earth objects have been found so far; it is believed that, very roughly, 2,000 such objects of at least one kilometer in size exist.
		The largest, the asteroids (1627) Ivar and (1580) Betulia, *7 are of similar size to that which caused the mass extinction 65 million years ago.
		None of the approximately 200 known objects are expected to collide with Earth for at least two centuries, although one of them (the asteroid 2340 Hathor) warrants special attention.
