Similarities of Uranus & Neptune
I’m Christopher Snead, a graduate student at UCLA’s Department of Earth and Space Sciences. Today, I’d like to discuss the similarities between Uranus and Neptune. Uranus and Neptune are the two most distant planets in the solar system, and they have a number of similarities. Aside from their physical appearance, they both have a similar color and a similar size. They also have similar atmospheric compositions. But, what’s most interesting is that although one is 19 astronomical units away from the sun – which is 19 times the distance from the Earth to the sun – and the other one is 30 astronomical units away, they both have remarkably similar internal temperatures, suggesting that their source of heat has something to do more with the heating of the sun and maybe some internal process.
