Abstract :
The Asteroid 21 Lutetia is the target of a flyby by the Rosetta spacecraft in mid-2010. We observed Lutetia with the Keck adaptive-optics system, and searched for satellites. We find none, to a flux limit of 1/350 (Δ-mag = 6.4), corresponding to a size limit of roughly 6 km, at a separation of 0.15″ (3 primary radii or 0.006 Hill radii).
