Taun Posted June 2, 2015 #2 Share Posted June 2, 2015 (edited) I know the article stated that if Ceres (for example) were in Earth's Orbit, it's ice would melt and it would gain an atmosphere, but be unable to hold it... I wonder how long a body that size could hold a viable atmosphere... Would it be just a few months/years... or hundreds even a few thousand?... Long enough for colonization and technology to extend the time? Edited June 2, 2015 by Taun Link to comment Share on other sites More sharing options...

The gravitation of such small bodies is so low so that the air pressure would also be extremely low, even with a thick atmosphere, too low for us to survive without a pressure suit.

Waspie_Dwarf Posted June 2, 2015 Author #4 Share Posted June 2, 2015 Long enough for colonization and technology to extend the time? Any civilization with the technology capable of moving an object the size of Ceres to the habitable zone is almost certainly going to have the technology not to need to move an object the size of Ceres to the habitable zone. 2 Link to comment Share on other sites More sharing options...
