Neptune and It 'Twin', Uranus

The Twins: They're same!
Uranus and Neptune usually called 'twin' by many people. Not just because they were in a very close distance and have almost same colors and characteristic, they also both called 'ice giants' because they're very cold planet. But different than Pluto, this two planets not just cold - they were big too, that's why those planets called ice giants. They were also two of four Jovian planet which are characterized by large sizes and masses but low mean densities (compared with Earth). As with Uranus, Neptune's distance from the Sun and its relatively small size compared to Jupiter and Saturn ensure that the planet is below the freezing point of its main constituents.


This is Uranus


The Twins: Which one better?
If they both are compared, I will choose Neptune, because besides I was selling and advertising this planet for sale (haha ^^), this planet had better (blue) color than the pale Uranus. Uranus is slightly larger than Neptune, but Neptune is considerably more massive and denser than Uranus. Uranus had 27 (or more!) satellite, but too much isn't good also, right?

Neptune had 13 satellites but one of them, Triton (one of Neptune's satellites) was bigger than any satellites around Uranus! Triton is the coldest object that has been measured in the solar system. Neptune's second known satellite, the irregular moon Nereid, has one of the most eccentric orbits of any satellite in the solar system. Neptune is the first planet that known by mathematical prediction rather than regular observation.Unexpected changes in the orbit of Uranus led astronomers to deduce the gravitational perturbation of an unknown planet. Neptune was found within a degree of the predicted position.
