Uranus is the seventh planet from the Sun. It's not visible to the naked eye.

Uranus is the first planet discovered with the use of a telescope. Uranus is tipped over on its side with an axial tilt of 98 degrees. It is often described as "rolling around the Sun on its side." There are many unexplained climate phenomena in Uranus's atmosphere, such as its peak wind speed of 900 km/h, variations in its polar cap, and its erratic cloud formation.

Uranus is the seventh planet from the Sun. It is a gaseous cyan-coloured ice giant. Most of the planet is made of water, ammonia, and methane in a supercritical phase of matter, which in astronomy is called 'ice' or volatiles. The planet's atmosphere has a complex layered cloud structure and has the lowest minimum temperature of −224 °C out of all the Solar System's planets.
