Another one that's been through a few drafts:
My star in the moonlight is white,
My star in the sunset is gold,
My star shines without making light,
My star is unpleasantly cold.
A point in a great constellation
When seen from below or afar,
At night, from a great elevation,
I stare from my star to a star.
What is my star?
(EDITED for improvements to verse and to remove dead giveaway clue.)
