American experts from the University of Idaho found that in the not too distant space standards the future some of the 27 moons of Uranus will face each other. It is expected that during the next million years, such a fate awaits the moons Cressida and Desdemona, as well as satellites under the name Cupid and Belinda.
The moons of Uranus are named after characters from English literature. Desdemona, the heroine of the famous plays of William Shakespeare “Othello”, Cupid appears in another of his work titled “Timon of Athens” and Cressida in the play “Troilus and Cressida”. Belinda is one of three moons of the ice giant, whose name was taken from Shakespeare and from Alexander Pope poem “the rape of the lock”.
The cause of the collision Desdemona and Cressida, according to the forecast of experts, will be the mass of the latter. As shown by a recent study Cressida has a much higher density than many of the smaller moons of Uranus are composed of water ice and porous in structure. Planetary scientists have suggested that Cressida, in contrast, consists mainly of carbonaceous matter. While to date, the orbit of Desdemona and Cressida located just 900 kilometers from each other, despite the fact that their diameter is 68 and 82 km respectively.
Experts also admit that in the past Uranium was more moons, but they had collapsed as a result of the earlier collision. This, in particular, could explain the presence of some of dusty rings around that planet.
Uranium — diameter and moons of the Solar system. Just like the gas giants of the Solar system, Uranus, in addition to many satellites, a ring system and magnetosphere. The only spacecraft photographed the Uranus from a close distance was “Voyager-2”. By the way, its “twin”, “Voyager 1” was launched exactly 40 years ago.
