Heavenly body from remote parts (6)
I believe the answer is:
meteor
'heavenly body' is the definition.
(meteor is a kind of heavenly body)
'remote parts' is the wordplay.
'parts' is an anagram indicator (the parts of the original word ordered differently).
'remote' anagrammed gives 'METEOR'.
'from' is the link.
(Other definitions for meteor that I've seen before include "extraterrestrial debris" , "It causes a streak of light in the night sky" , "Body entering earth's atmosphere" , "Remote sort of heavenly body" , "Space traveller" .)
