Spherical body (3)
I believe the answer is:
orb
'spherical body' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for orb that I've seen before include "A poetic eye, bro" , "A sphere or globe" , "Ornamental globe" , "Spherical object or shape" , "Ceremonial globe carried by a monarch" .)
