A few more:
Alun Hoddinott: The Sun, the Great Luminary of the Universe
Peter Sculthorpe: Sun Music I, II, III, IV
Nielsen: Helios Overture (a day in the life of the sun)
Stravinsky: The King of the Stars
Pichl: Symphony in D (Mars)
Koechlin's Seven Stars Symphony doesn't qualify - it's about movie stars.
But there's always Rock around the Clock (Bill Haley and the Comets)...
