    $\begingroup$ In the worldbuilding stack exchange there are many questions and answers which mention the minimum and maximum mass of habitable worlds. My answer here: worldbuilding.stackexchange.com/questions/200498/… Has links to other questions discussing the masses and sizes of habitable worlds, as well as to scientific articles discussing that subject. $\endgroup$

  • $\begingroup$ Given that we don't properly understand the atmospheric masses of terrestrial planets and moons, this is very hard to answer. In general, the capability to hold atmospheric mass goes exponential with the planet mass, when not growing into a gas giant, but those are upper limits. $\endgroup$
