Uranus is the third last planet in the Solar System and is located right before Neptune. This is so far out that the Sun's rays do reach here, but they don't provide enough warmth to melt the ice. Yeah, your eyes aren't betraying you! Uranus does have water! It's just frozen up ! Uranus' atmosphere consists of 83% hydrogen, 15% helium, and 2% methane. Uranus is at a distance of 2.9634 BILLION kilometers from the Sun! It takes almost 2 HOURS for the rays from the Sun to reach Uranus. One year here is equal to 84 years on Earth! One day here is equal to a whopping 58d 15h 30m on Earth! It has a radius of 25,352 kilometers from its core. Its core is also made of icy materials. Uranus has a frigid core, unlike almost all other planets who have rocky-molten cores. The core takes up about 80% of the planet's mass. The core mostly consists of water, ammonia, etc. Uranus has very faint rings that are hardly visible.
