THE TEN LARGEST ASTEROIDS.

The Ten LARGEST Asteroids, together with their rotation periods, arranged in descending size order are as follows:-

1. Ceres 9.075 hours, ie:- (9.075 ÷ 24) = 0.3781 Earth days.

2. Pallas 7.811 hours, ie:- (7.811 ÷ 24) = 0.3255 Earth days.

4. Vesta 5.342 hours, ie:- (5.342 ÷ 24) = 0.2226 Earth days.

10. Hygeia 27.659 hours, ie:- (27.659 ÷ 24) = 1.1525 Earth days.

704. Interamnia 8.727 hours, ie:- (8.727 ÷ 24) = 0.3636 Earth days.

511 Davida 5.13 hours, ie:- (5.13 ÷ 24) = 0.2137 Earth days.

65 Cybele 4.041 hours, ie:- (4.041 ÷ 24) = 0.1684 Earth days.

52 Europa 5.631 hours, ie:- (5.631 ÷ 24) = 0.2346 Earth days.

87 Sylvia 5.183 hours, ie:- (5.183 ÷ 24) = 0.2159 Earth days.

451 Patientia 9.727 hours, ie:- (9.727 ÷24) = 0.4053 Earth days.

To verify that these are the ten LARGEST asteroids, here is a scan from the book Asteroids, Their Nature and Utilization, by Charles T. Kowal (Senior Project Engineer at The Applied Physics Laboratory, Laurel, Maryland, USA.), published by John Wiley and Sons, 1996, Table 2.1

Below, we see scans from The Planetary Scientist’s Companion, by Lodders and Fegley, published by Oxford University Press, 1998, Table 13.7 to show the rotation periods of the Ten LARGEST Asteroids.
