Head after meteor travelling in distance (10)
I believe the answer is:
remoteness
'distance' is the definition.
(I know that remoteness is a type of distance)
'head after meteor travelling' is the wordplay.
'head' becomes 'ness' (ness is a headland).
'after' says to put letters next to each other.
'travelling' indicates an anagram.
'meteor' with letters rearranged gives 'remote'.
'ness' put after 'remote' is 'REMOTENESS'.
'in' acts as a link.
(Other definitions for remoteness that I've seen before include "Distant quality" , "Aloof manner" , "Far-off quality" .)
