Its closest planetary neighbor is Uranus. The low temperatures are such as have never been attained by Neptune. In fact, Neptune is more than 1 billion miles away from Uranus. Like Jupiter and Saturn, the atmosphere of the planet is also composed mainly of Hydrogen and Helium gases. As already mentioned, Uranus is the coldest planet, although Neptune and Pluto are located much further from the Sun. Its core is not very hot where as Neptune (which is further away) has a hotter core and is more active.

The pinkish colour of the one pole we see looks like a giant eyeball considering the rest of the planet appears to be a turquoise shade, it's tilt is about 98 degrees. Why can Uranus reach colder temperatures when it receives considerably more solar light? This is slightly more than Neptune (0.29) which is another reason why Uranus is colder than Neptune even though it is closer to the sun. Recent evidence points to the very fine dust also being spread across the planet by water, backed up by the presence of channels and ducts across the surface of Mars.
