Moons of Uranus on a collision course: Study
US-based researchers have found evidence that two pairs out of Uranus' 27 known moons are on a collision course. The study revealed Cressida, which currently orbits Uranus just 900 km from Desdemona, is slowly pulling the moon towards it and would crash within a million years. Researchers found the same to be true for another pair Cupid and Belinda.
