The Lightcurve Data Base assumes an S- or C-type to be equally likely, using an averaged value for its albedo (see below).
[4][a] In September 2007, a rotational lightcurve of Vʹyus was obtained from photometric observations by Maurice Clark at the Montgomery College Observatory in Maryland, United States.
Lightcurve analysis gave a well-defined rotation period of 6.587 hours with a brightness amplitude of 0.85 magnitude (U=3).
