Researchers Confirm Three Asteroids Are Co-Orbital with Uranus
Astrophysicists from the Complutense University of Madrid have confirmed that Crantor, a large asteroid with a diameter of 70 km has an orbit similar to that of Uranus and takes the same amount of time to orbit the Sun. Researchers have demonstrated for the first time that this and a further two objects of the group of the Centaurs are co-orbital with Uranus.
Uruguayan astronomer Tabaré Gallardo suggested in 2006 that the asteroids Crantor and 2000 SN331 complete their orbits of the Sun in the same time period as Uranus – an orbit of approximately 84 Earth years. Now two researchers at the Complutense University of Madrid (UCM) have confirmed that in the case of Crantor this is true.
