Remote designed for object in the sky (6)
I believe the answer is:
Here is my best explanation:
'object in the sky' is the definition.
'remote designed' is the wordplay.
'designed' indicates anagramming the letters (designed with the letters).
'remote' with letters rearranged gives 'meteor'.
'for' is the link.
(Other definitions for meteor that I've seen before include "Remote type of heavenly body", "Streak of light in the night sky", "Small extraterrestrial body", "sky phenomenon", "Space traveller", "streaker?", "Piece of matter in the solar system", "Solar System body", "lump of rock" and "A space-traveller".)
