What would the temperature on the moon be if it had a atmosphere?

Answer 1

If the moon had enough mass to maintain an earth like atmosphere it would likely be a very unpleasant place. Because the moon has a rotational period of a little over 14 days any single point on the moon is exposed to the sun or in dark for a little over 14 days at a time. This would likely lead to boiling hot "days", 14+ earth days long, and freezing cold "nights", also 14+ earth days long.

Also, just as a side note, the moon has gravity.

Answer 2

The temperature on the moon would vary depending on the composition and density of its atmosphere. With a thick atmosphere, temperatures could range from -100°C to 100°C due to the trapping of heat. However, different gases in the atmosphere would result in different temperature profiles.

Answer 3

The moon doesn't have any atmosphere or weather. It is very dead, and the only thing that disturbs the surface of the moon is the occasional collision of a meteorite, producing its many craters.

The long term forecast for the moon is a very cold night followed by a very warm day for the next several thousand years, with zero percent probability of precipitation. All of the days are going to be sunny, except for the occasional terrestrial eclipse.

Answer 5

The Earth's atmosphere has no effect on the moon. Do you think the atmosphere reaches that far? The atmosphere only goes up about 200 miles, and the moon is a quarter of a million miles away from the Earth.

Answer 6

The temperature would depend on the density and composition of the atmosphere. The moon might have a hard time holding on to an atmosphere due to low gravity and tidal forces pulling from Earth. Also, solar wind would tend to strip an atmosphere away because of a lack of magnetic fields, Van Allen belts, and magnetosphere on the moon. So there is no way to say a temperature. This question is a little like asking "if pumpkins had wings, how high would they fly".

Answer 7

The Moon has been orbiting the Earth for something upwards of 4 billion years. It's not going anywhere.

If we humans are as smart as we pretend to be, we'll plant lunar colonies and inhabit the Moon; and Mars, and the larger asteroids, and perhaps some of the Jovian moons. Having all the human beings stuck here on one fragile little planet makes our species vulnerable to cosmic accidents and extinction.

In August of 1883, we may have just barely escaped extinction; new analysis indicates that the fragments of a billion-ton comet may have passed within a couple thousand miles of the Earth. That's comparable in size to the object that impacted the Earth 65 million years ago and killed off 75% of all life on the planet - including the dinosaurs.

Answer 8

Mass: 7.3477 x 1022 kg

Temperature: 130 K (-143 C) to 220 K (-53 C)

Atmosphere: none

Answer 9

if the moon had an atmosphere than it would also, of course, have weather. this would mean that all markings, footprints, and impact craters would eventually be wiped from the surface.

Answer 10

The Moon doesn't have an atmosphere to speak of.
