Two pairs of Uranus moons are located on the collision course. The planet occupies the 7th position in distance from the Sun. This ice giant has 27 satellites. They carry out a turn around Uranus and are extremely small. But research shows that some of them are aimed at hitting.
Scientists carefully examined the rings and noticed that their shape is odd. This is something like a triangle. This was caused by the attraction of Cressida (one of the moons). Its gravity is enhanced because the satellite moves in time with the planetary orbit.
The particles from the rings move faster than the moon, therefore they create an odd orbital shape. Upon detailed study, it turned out that Cressida was set up to collide with Desdemona, which is now distant from the first one by 900 km. The process will take a million years. The same waits for Cupid and Belinda.
