Trips around the world? (6)
I believe the answer is:
orbits
'trips around the world?' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for orbits that I've seen before include "Curved paths of planets" , "Circulates" , "Paths of celestial bodies around others" , "Curved paths of celestial objects" , "Elliptical courses of celestial objects" .)
