Sit and adore rippling body (8)
I believe the answer is:
asteroid
'body' is the definition.
(I've seen this before)
'sit and adore rippling' is the wordplay.
'and' means one lot of letters go next to another.
'rippling' indicates anagramming the letters.
'sit' put after 'adore' is 'adoresit'.
'adoresit' is an anagram of 'ASTEROID'.
(Other definitions for asteroid that I've seen before include "circling rock" , "space traveller" , "Small heavenly body" , "Small body orbiting sun" , "Minor planet" .)
