Abstract (from CDS):

R. Miles, Stourton Caundle, Dorset, UK, reports that photometric observations of minor planet 2008 HJ (cf. MPEC 2008-H26, MPO 139312), obtained using the 2.0-m Faulkes Telescope South during Apr. 28-29, reveal that this Apollo-type object has the shortest known rotation period of any natural body in the solar system at 42.67 ± 0.04 s. It exhibits a light curve comprised of two similar maxima and minima with an amplitude of 0.8 mag. Assuming an absolute magnitude of H = 25.8 and a geometric albedo of 0.2, 2008 HJ has presumed approximate dimensions 12 x 24 m. The fastest previously known rotator was 2000 DO8, which has a rotation period of 78 s (Whiteley et al. 2002, Icarus 157, 139).
