Based on their idea of its mass and also its position in space, they say it is either a rocky super-Earth, or a gaseous mini-Neptune – also sharing characteristics with Uranus or Neptune, making it an icy planet with a solid core.

Which planet is the hottest?

Venus’ thick atmosphere traps heat creating a runaway greenhouse effect – making it the hottest planet in our solar system with surface temperatures hot enough to melt lead. The greenhouse effect makes Venus roughly 700°F (390°C) hotter than it would be without a greenhouse effect.

Which planet is the coldest?

Uranus holds the record for the coldest temperature ever measured in the Solar System: a very chilly -224℃. The temperature on Neptune is still very cold, of course – usually around -214℃ – but Uranus beats that. The reason why Uranus is so cold is nothing to do with its distance from the Sun.
