Falling star, remote, exploded (6)
I believe the answer is:
meteor
'falling star' is the definition.
(synonyms)
'remote exploded' is the wordplay.
'exploded' indicates anagramming the letters.
'remote' is an anagram of 'METEOR'.
(Other definitions for meteor that I've seen before include "Component of shower" , "rock falling to earth" , "Glowing heavenly body" , "streaker?" , "fighter" .)
