Heavenly body is remote, I do fancy (9)
I believe the answer is:
Here is my best explanation:
'heavenly body' is the definition.
(meteoroid is a kind of heavenly body)
'remote i do fancy' is the subsidiary indication.
'fancy' indicates anagramming the letters.
'remoteido' with letters rearranged gives 'meteoroid'.
'is' is the link.
(Another definition for meteoroid that I've seen is "heavenly body".)
