● Explain a unique feature about Uranus. // help me please

Physical characteristics

Uranus is blue-green in color, as a result of the methane in its mostly hydrogen-helium atmosphere. The planet is often dubbed an ice giant, since at least 80% of its mass is a fluid mix of water, methane and ammonia ice

Imagine a pool that size. Uranus comes in second as the least dense planet. What this means that instead of floating, Uranus would actually sink in water. ... Even though Uranus is 14.5 times as massive as the Earth, you would only experience about 89% the force of gravity if you could stand on its surface

While all the other planets spin like tops around the sun, Uranus lies on its side. It isn't the farthest planet from the sun, yet it manages to be the coldest. ... It's so far away, and its movement so slow, that it was originally thought to be a star until Sir William Herschel revealed its planetary nature in 1781
