and Earth crosser. It has been designated a Potentially Hazardous Asteroid (PHA) by the Minor Planets Center (MPC) and as such has been the target of Doppler studies at Goldstone (Ostro & Giorgini 2004; Benner et al. 2008; Gavrik & Gavrik 2008) on November 2002 and 2010. These radar observations suggest that its near-surface is extremely rough.

A preliminary rotational period of 13.5 h with a light curve amplitude $>$ 0.8 mag (indicating a very elongated body) and an estimated size of 260 m were found by Pravec, Wolf & Sarounova (2010)[^2]. Bessel $BVRI$ photometry (Barajas et al. 2011)[^3] has showed that 2002 VE$_{68}$’s mean colors are compatible with those of an X-type asteroid, perhaps similar to the E-type asteroid 2867 Steins (but also 1114 Lorraine, 5294 Onnetoh, 796 Sarita, 107 Camilla or 3686 Antoku). Barajas et al. (2011) also calculated a synodic period of 13.5 h (confirming the previous preliminary value), an albedo of about 0.25 and an absolute visual magnitude of 20.59 that gives an effective diameter of about 200 m (also consistent to preliminary determinations). With an amplitude of 0.9 mag, its light curve suggests that it may be a contact binary in which two rubble piles
