MASS AND DENSITY OF THE B-TYPE ASTEROID (702) ALAUDA
Abstract
Observations with the adaptive optics system on the Very Large Telescope reveal that the outer main belt asteroid (702) Alauda has a small satellite with primary to secondary diameter ratio of {approx}56. The secondary revolves around the primary in 4.9143 {+-} 0.007 days at a distance of 1227 {+-} 24 km, yielding a total system mass of (6.057 {+-} 0.36) x 10{sup 18} kg. Combined with an IRAS size measurement, our data yield a bulk density of 1570 {+-} 500 kg m{sup -3} for this B-type asteroid.
