Distant meteor exploded (6)
I believe the answer is:
remote
'distant' is the definition.
(I know that distant can be written as remote)
'meteor exploded' is the wordplay.
'exploded' indicates anagramming the letters.
'meteor' with letters rearranged gives 'REMOTE'.
(Other definitions for remote that I've seen before include "Distant, aloof" , "Distant - meteor (anag)" , "Slight possibility" , "Device for controlling apparatus from a distance" , "device used by couch potato?" .)
