Earth, north and south, moving Captain Kirk? (7)

I believe the answer is:

shatner

I'm a little stuck... Click here to teach me more about this clue!

'captain kirk?' is the definition.
I know nothing about this answer so I can't tell whether it can be defined by this definition.

'earth north and south moving' is the wordplay.
'north' becomes 'N' (abbreviation).
'and' is a charade indicator (letters next to each other).
'south' becomes 's' (abbreviation).
'moving' indicates anagramming the letters (letters are moved around).
'earth'+'n'+'s'='earthns'
'earthns' with letters rearranged gives 'SHATNER'.

Can you help me to learn more?

(Another definition for shatner that I've seen is " William -- (Captain Kirk actor)".)
