Uranus is the seventh planet from the Sun. It has the third-largest planetary radius and fourth-largest planetary mass in the Solar System. Uranus is similar in composition to Neptune, and both have different bulk chemical composition from that of the larger gas giants Jupiter and Saturn. read more

Far, far from the sun, Uranus has a blue-green atmosphere that hints at its makeup. One of the two ice giants, the planets composition differs somewhat from Jupiter and Saturn in that it is made up of more ice than gas. read more

Jupiter and Saturn are the gas giants of the Solar System. The term "gas giant" was originally synonymous with "giant planet", but in the 1990s it became known that Uranus and Neptune are really a distinct class of giant planet, being composed mainly of heavier volatile substances (which are referred to as "ices"). read more

While other gas giants are powered by their cores, Uranus radiates almost no excess heat into space. One reason for this could be due to an impact soon after the planet's formation. The planet's current sideways rotation, spinning at a 90-degree angle compared to the other planets in the solar system, already indicates a collision. read more
