The Moon’s tectonic activity is dead now and has been for millions of years, but there is still some geological activity in the mantle and the core of the Moon.

In reply to Mike.

We know for sure, because we have sent a dozen people to the Moon!
They made some tests while they were there.
Also it’s possible to detect atmospheres with a powerful telescope. Each atom leaves a trace in the reflected light we observe from the Moon (or any other planet, or other celestial body).

There also are more factors that come into play with an object like the Moon other than just relative gravity. The Moon’s small gravity and relative flatness doesn’t hold up well against forces like the solar wind. Also the Moon cooled off very quickly so its geological processes have been dead for a long time.

So very interesting and even still how they know for sure and have found water on the moon now. In the very bottom of dark canyons and craters on the moon that are never touched by sunlight. It’s water that’s got there from other planets and meteors hitting the moon and freezing there forever basically.
