What is the temperature on the moon?

The temperature on the moon can reach a blistering 250° Fahrenheit (120° Celsius or 400 Kelvin) during lunar daytime at the moon's equator, and plummet to -208 degrees F (-130° C, 140 K) at night. 

In certain spots near the moon's poles temperatures can drop even further, reaching - 424° F (- 253°C or 20 K) according to NASA.

One reason for these dramatic extremes is that the moon has no lunar atmosphere to insulate heat. Its lack of a gaseous blanket also means that craters and major dramatic landmarks do not erode the way they do on Earth, leaving perpetual pockets of darkness near the moon's poles that host the moon's most frigid temperatures.
