Oxford PAT 2014, Question 10

  1. I know that Uranus and Neptun are made by Helium and Hidrogen, but they are also clasified as ice giants, not gas giants. What do you think?

    1. Hi Dan. Yes you are absolutely right that Uranus and Neptune tend to be classified as ‘ice giants’ and not ‘gas giants’ these days. This is because they are not mostly composed of H and He (like Jupiter and Saturn are), but also have a large amount of constituents classified as ‘ices’, like water, ammonia etc.

      But here we are only given the choice between two classes of planet: gas giants and rocky planets. Uranus and Neptune are definitely not rocky planets, so calling them gas giants is correct here, I think.
