I find it hard to believe that they can so openly say that it is one of the coldest places in the solar system.

The moon has been explored more times than any other celestial body in the solar system besides earth. So wouldnt it be very likely that, since they only just now discovered the coldest place on the moon that they would find colder places on other celestial bodies too? And other celestial bodies being further away from the sun, would'nt the chances of others being colder than the moon more likely?
