    Extreme Temperatures of The Solar System

    Some of you may be familiar already with the following comparisons—but take a moment to think about what they really mean, in relation to the normal temperatures of human experience. 

    The sun—to borrow an understatement from an earlier entry—is pretty hot. It’s at its hottest in the centre, which reaches around twenty-seven million Fahrenheit (fifteen million Kelvin).

    In comparison, it’s actually less than ten thousand degrees Fahrenheit at its surface (about 5,700 K).The centre of the Earth stands at about the same temperature as the surface of the sun.

    Apart from the sun’s centre, the hottest part of our solar system is the core of Jupiter, which, remarkably, is five times hotter than the Sun’s surface.

    And the coldest-known place? That’s actually on our own moon, where temperatures in the shadows of some craters are only thirty Kelvin above absolute zero.

    The temperatures, measured by NASA’s Lunar Reconnaissance Orbiter, are even colder than those on Pluto.
