The Moon has the coldest place in the Solar System measured by a spacecraft.

Nasa's Lunar Reconnaissance Orbiter has used its Diviner instrument to probe the insides of permanently shadowed craters on Earth's satellite.

It found mid-winter, night-time surface temperatures inside the coldest craters in the northern polar region can dip as low as minus 249C (26 Kelvin).

"The Moon has one of the most extreme thermal environments of any body in the Solar System," said Prof David Paige.

"During the middle of the day, temperatures can get up to about 400K (127C) at the equator; and at the poles at night, they can get very cold," the Diviner principal investigator at the University of California, Los Angeles, added.

But since there's no atmosphere to speak of, the wind chill is negligible.
