Long-tailed celestial body orbiting the sun (5)

I believe the answer is:

comet

(Other definitions for comet that I've seen before include "Small extraterrestrial body" , "Celestial body with luminous tail" , "Celestial orbiter" , "Halley's phenomenon in space" , "Halley's space traveller?" .)

I've seen this clue in the Sydney Morning Herald.
