Minor planets and related objects. XIV - Asteroid /4/ Vesta

Gehrels (1967), investigating the direction of Vesta's pole, found that his light curves exhibited two distinct maxima. An analysis of all available light curves over the period from 1950 to 1973 shows that Vesta has a true period of 10h40m58s.84 (+ or - 0s.01 p.e.) with two maxima and two minima. Vesta's rotation is direct. The shape is that of a spheroid, with one diameter exceeding the other two by roughly 15%, and with an apparent shape irregularity near the south pole.-
