Distant meteor disintegrated (6)
I believe the answer is:
remote
'distant' is the definition.
('remote' can be similar in meaning to 'distant')
'meteor disintegrated' is the wordplay.
'disintegrated' indicates anagramming the letters.
'meteor' is an anagram of 'REMOTE'.
(Other definitions for remote that I've seen before include "Controller of programmes" , "Far removed" , "Far off; outside (chance)" , "in the middle of nowhere" , "Unlikely" .)
