The Constellation Equuleus

Equuleus is the second-smallest of the modern constellations, and perhaps the most insignificant.

It contains no stars brighter than mag 3.9, and no deep sky objects brighter than thirteenth magnitude.

Its name is Latin for ‘little horse’ or foal. So small is the constellation that there is only space to depict the horse's head. It lies next to the much larger horse Pegasus.

Accounts vary as to horse's identity in Greek mythology.
