Orbiting body like spinning wheel (6)
I believe the answer is:
saturn
'orbiting body' is the definition.
I can't tell whether this defines the answer.
'like spinning wheel' is the wordplay.
'like' becomes 'as'.
'spinning' shows that the letters should be reversed in order.
'wheel' becomes 'turn' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'as' back-to-front is 'sa'.
'sa'+'turn'='SATURN'
Can you help me to learn more?
(Other definitions for saturn that I've seen before include "Planet with concentric rings" , "Massive body ringed" , "Roman god - planet" , "Turn as a planet" , "orbits the sun" .)
