Star missile (7)

I believe the answer is:

polaris

I believe this is a double definition.

'star' is the first definition.
(star within the constellation Ursa Minor)

'missile' is the second definition.
(I've seen this before)

(Other definitions for polaris that I've seen before include "star (non-movie)" , "Star near the N pole of the heavens" , "North Star - missile" , "Star useful for navigation" , "weapon sailors unleash" .)

I've seen this clue in The Globe and Mail.
