Uranus occupies the seventh position in the Solar system. It has the third largest planetary radius and fourth largest planetary mass among the planets of the Solar System. Composition of Uranus and Neptune are similar but it differs in chemical combination to the larger gas giants like Jupiter and Saturn.
Uranus and Neptune are placed in a separate category known as ‘ice giants’ by Astronomers. Uranus’s atmosphere contains hydrogen and helium much akin to the atmosphere of Jupiter and Saturn. However the atmosphere of Uranus contains more ice, such as water, ammonia, and methane. There are some traces of hydrocarbons also. It is also the most frigid and coldest planetary atmosphere in the Solar System with the lowest temperatures reaching −224.2 °C. The interior of Uranus is mostly composed of ices and rocks.
Uranus is the seventh planet in the Solar System. This ice giant is composed mainly of ice particles, hydrogen, and helium. It has a very unusual, elliptical orbit with a 99 degrees axial tilt. Latest studies by a group of researchers are saying that the blue planet has an unlikely twin some 25000 light years away.
The axis tilt and the composition of the planet cannot be determined because of the distance, 25000 light years away, astronomers are optimistic enough with their measurement to call it Uranus’s twin. One may ask, why this clamor for this particular ice giant, there are a lot many ice giants which are moving around the universe. Andrew Gould of Ohio State University says that we are lucky to have a twin so close like the one above and it gives astronomers the opportunity to compare and contrast, potentially learning more about how ice giants form in solar systems like ours.
Gould said in a statement, highlighting one of the mysteries he and his colleagues hope to solve “Nobody knows for sure why Uranus and Neptune are located on the outskirts of our solar system, when our models suggest that they should have formed closer to the Sun. One idea is that they did form much closer, but were jostled around by Jupiter and Saturn and knocked farther out.”
The Uranus twin seems to have endured a similar jostling much like those found in a binary star system. While the planet orbits one star its orbit is affected by the attraction of a second nearby star.
