Orbiting body like spinning wheel (6)
I believe the answer is:
saturn
'orbiting body' is the definition.
I can't judge whether this definition defines the answer.
'like spinning wheel' is the wordplay.
'like' becomes 'as'.
'spinning' says the letters should be written in reverse.
'wheel' becomes 'turn' (I can't explain this - if you can you should believe this answer much more).
'as' in reverse letter order 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" .)
