Hyginus is a lunar caldera located at the east end of the Sinus Medii. It was named after ancient Roman astronomer Gaius Julius Hyginus.[1] Its rim is split by a 220 kilometer-long rille, Rima Hyginus, that branches to the northwest and to the east-southeast. The crater is deeper than the rille, and lies at intersection of the rille's branches. Together, the crater and the rille form a prominent feature in an otherwise flat surface. Smaller craters along the length of the rille may have been caused by the collapse of an underlying structure.[citation needed]
Hyginus is one of the few craters on the Moon that was not created as a result of an impact, and is instead believed to be volcanic in origin. It lacks the raised outer rim that is typical with impact craters.[citation needed]
Hyginus was considered a possible landing site during the
It was near Hyginus that in 1878 Hermann Klein claimed to have discovered a new crater.[4]

By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Hyginus.
