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 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) × 1018 kg. Combined with an IRAS size measurement, our data yield a bulk density of 1570 ± 500 kg m-3 for this B-type asteroid. Because B-type asteroids may represent relatively primitive material with similarities to carbonaceous meteorites [1, 7, 9], their characterization can further our understanding of the primordial building blocks of planets. Full results are published in the Astrophysical Journal, Vol 727, p. 69.
