Round-the-world trip (5)

I believe the answer is:

orbit

'round-the-world trip' is the definition.
(I've seen this in another clue)

This is the entire clue.

(Other definitions for orbit that I've seen before include "Planet's course" , "Sphere of activity" , "fly in a circle" , "Field of influence" , "Go round" .)

I've seen this clue in The Wall Street Journal and The Irish News.
