Mix a Puerto Rican cocktail for nearby star (7,8)

I believe the answer is:

proxima centauri

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

'nearby star' is the definition.
'proxima centauri' can be an answer for 'star' (I've seen this before). I am unsure of the 'nearby' bit.

'mix a puerto rican cocktail' is the wordplay.
'cocktail' is an anagram indicator.
'mix'+'a'+'puerto'+'rican'='mixapuertorican'
'mixapuertorican' anagrammed gives 'PROXIMA CENTAURI'.

'for' acts as a link.

Can you help me to learn more?

(Another definition for proxima centauri that I've seen is " star".)

I've seen this clue in The Everyman puzzle in The Observer.
