Earth is the third planet from the Sun, and so far the only planet known capable of supporting life. The average temperature on Earth is 7.2°C, but it varies much more than that at its extremes. The hottest temperature ever recorded on Earth was 70.7°C in Iran. The lowest temperature was -89.2°C in Antarctica.

With temperatures dropping to -218°C in Neptune’s upper atmosphere, the planet is one of the coldest in our Solar System. Like all of the gas giants, Neptune has a much hotter core, which is around 7,000°C.
