Space rock: Dicky adores it (8)
I believe the answer is:
'space rock' is the definition.
(I've seen this in another clue)
'dicky adores it' is the wordplay.
'dicky' indicates an anagram (dicky can mean ill or non-functioning).
'adoresit' is an anagram of 'ASTEROID'.
(Other definitions for asteroid that I've seen before include "Small rock orbiting the sun" , "Rocky body in orbit" , "Piece of rock that moves around the heavens" , "way-out rock" , "space traveller" .)
