Not on its own for long time periods, but in the short term or with some human ingenuity it would probably be sustainable.It won't effect earth at all, and the moon would not be able to sustain an earth-like atomsphere due to it's low gravity.
well thats what my original question was about. If moon gets an atmosphere how will it affect earth, doesn't matter how it gets an atmosphere as long as it has one. ppl started talking about ribs and sauce. damn you hijackers.Yeah, but not directly. The atmosphere would require stronger gravitational field than moon has now which would effect earth.
Otherwise this has already degraded into spam.
Yep.well since we're talking about gravity. in order for a stelar body to even have an atmosphere it needs a strong gravitational pull? thats why earth has an atmpsphere and other planets don't cuz of gravity power?
Ribs is a much better topic and you know itwell thats what my original question was about. If moon gets an atmosphere how will it affect earth, doesn't matter how it gets an atmosphere as long as it has one. ppl started talking about ribs and sauce. damn you hijackers.
If magicaly the Earth's moon got an atmosphere will Earth be affected in any way?
That's only partially correct. It's not really needed to have an atmosphere, it is just needed to hold an atmophere, and numerous other factors (temperature/composition/magnetic fields/solar wind) also have an important impact. Titan (saturn's moon) has a very thick atmophere despite having similar gravity to our moon.well since we're talking about gravity. in order for a stelar body to even have an atmosphere it needs a strong gravitational pull? thats why earth has an atmpsphere and other planets don't cuz of gravity power?
Well, he didn't say what kind of atmophere though. It could make the moon even more hostile.The ensuing landgrab could be the cause of war and other strife until the issue of who owns the moon is decided.
You think treaties ever stopped anyone?EDIT: Wiki says no one.

iWell, he didn't say what kind of atmophere though. It could make the moon even more hostile.
Changed to the correct smilie Don't worry Perf,You think treaties ever stopped anyone?
Of course it would, but I'd reckon not on a human timescale.As per Perfections comment, the atmosphere would vanish.
It could most certainly have the same pressure as on Earth.I'm not even sure it would stay around for millions of years, but supposing it did, it still wouldn't follow the same density gradient as earths atmosphere and thus would very likely not produce the pressure (or oxygen concentration) at ground level necessary to sustain humans that aren't in spacesuits.
Yeah it would, having just to condition an already existant atmophere is a heck of a lot easier then creating one from scratch.So it would make absolutely no difference to anybody except the hordes of scientists trying to figure out how it got there.
If it has the same the same temperature/density/and composition as air on Earth then by the ideal gas equation it must have the same pressure.[EDIT] I was assuming the question meant an "earthlike" atmosphere, i.e. a sphere of air would suddenly appear around the moon which temporarily causes earthlike atmospheric density at groundlevel.
I'm not convinced of this at all. Theres all kinds of considerations such as how the tidal lock or solar heating will affect it (since all the measurements are different: surface area, "thickness" of the atmospheric layer etc.)It could most certainly have the same pressure as on Earth.
Well I was sloppily applying "use" as in, being able to live on the surface. If you are right on A) then ok, sure, but if A) is wrong then what could you do? Sell the air?Yeah it would, having just to condition an already existant atmophere is a heck of a lot easier then creating one from scratch.
Who says it will have the same temperature? and same density again depends on A)If it has the same the same temperature/density/and composition as air on Earth then by the ideal gas equation it must have the same pressure.
