From Wikipedia, the free encyclopedia
Testudo (Latin for turtle) was a constellation located between the constellations of Cetus and Pisces, today constituting a natural but faint asterism composed from the stars 20, 27, 29, 30 and 33 Piscium,[1] where the star 20 is intended to be the head of the turtle. The origin of the constellation is uncertain, but it is alleged that it was created by an astronomer William Henry Smyth in the 18th century[2]. It is no longer recognized.
