Uranus is the planet in the solar system that is primarily known for its blue color. This distinctive hue is due to the presence of methane gas in its atmosphere, which absorbs red light and reflects blue. As the seventh planet from the Sun, Uranus is unique not only for its color but also for its rotational tilt; it rotates on its side. Additionally, Uranus is one of the coldest planets, with temperatures dropping extremely low. The planet has a collection of faint rings and numerous moons, adding to its intriguing characteristics within our solar system.
