The seventh planet from the Sun, classified as an ice giant. Uranus is basically a large
ball of hydrogen, methane, helium, and, to a lesser extent, ammonia which imparts a
blue color. It is also very
cold, with temperatures in the neighbourhood of 357°
F (-216° C).
The name has become the
butt (pun not intended) of many ass jokes; I think you can see why.
Some astronomers pronounce it, "ūr′·ə·nəs" (YERR'uh ness) in order to help stem the tide of Uranus-related ass jokes while others still prefer the original pronunciation, "ū·rā′·nəs" (your ANUS).
