Uranus is a blue and greenish color due to the methane in its atmosphere. It has a very light ring system that is hardly seen, with only nine rings clearly seen. Clouds can also be seen near the southern part of the planet and it seems a little a wider than other planets because of its large diameter. On dark days Uranus is seen as a bright star because it has a brightness of +5.5 and +6.0. Another intriguing fact about its appearance is that a dark spot has been spotted with the Hubble telescope, suggesting that the atmosphere is more like neptune.
