The cold of space is one heck of a heat sink. Any heat that a meteoroid might
get from the sun while in space, could easily re-radiate back into space as
infrared(Heat). If for some reason any of this heat from the surface may find
it's way thru the interior and on to the other side, it will still re radiate
into space...particularly if we are talking about a relatively small object.
Entropy goes from hot to cold. If there were any heat to an object, there
will always be the natural direction for heat to flow towards the cold. There
will be no natural effort for the heat to stay within the object as long as
there is the cold of space to absorb it. rotating or not, space is cold on
all sides of the meteoroid.
