VULPECULA
(Abbreviation:
Vul).
Originally Vulpecula
et Anser, the Fox and Goose
nowadays the goose has disappeared (possibly the fox has eaten it). Vulpecula contains no star above magnitude 4.4, and is
notable only because of the presence of the dumbbell Nebula and the fact that
several novæ have appeared within the boundaries of
the constellation.
