Uranus-Neptune

Planet Uranus
Uranus is the seventh from the sun and little smaller than Saturn gas giant. It is also made mostly of hydrogen and helium, contains ice and thus also called ice giant. It has the coldest atmosphere -224 Celcius degrees, 27 moons and a ring system. 1 Uranus year= 84 Earth years, and 1 rotation lasts 18 hours. The unique about this planet is that it rolls on its orbit and the rings around it are vertical and look like a target.

Planet Neptune
The eighth and last gas and ice giant is *Neptune*. It can be named as Uranus smaller twin. It has four thin rings, 13 satellites and a turbulent atmosphere with a Great Dark Spot. Like the other gas giants has high core temperature that becomes extremely cold (-218 Celcius) on the upper atmosphere and similar to Uranus possesses a major amount of ice. 1 Neptune year= 165 earth years and 1 Neptune day = 16 hours.
