As backyard astronomers saunter through the high northern summer skies, they eventually meet eye-to-eye with ancient Draco the Dragon. Within the circumpolar constellation lies a wealth of stars and deep sky objects, including carbon stars such as UX Draconis. UX Draconis is a pulsating and variable carbon star that shines with a rich orange-red color for all to enjoy.
UX Draconis shines at an average magnitude of +6.2, but since it’s a variable star, its magnitude range is between +5.94 to +7.1. It’s classified as a C-N5 star with a “cool” temperature of 3,480 Kelvin.1

I’ve seen other carbon stars that almost look like cherry red. For me, UX Draconis falls in line with the more orange variety like VY Ursae Majoris. It still makes for a lovely fine on late summer nights.
