eponym=C. Julius HyginusHyginus is a small lunar
caldera located at the east end of theSinus Medii . The crater rim is split by a long, linearrille that branches to the northwest and to the east-southeast for a total length of 220kilometer s. The crater is deeper than the rille, and lies at the bend where they intersect. Together the Hyginus crater and "Rima Hyginus" form a distinctive and prominent feature in an otherwise flat surface. Smaller craterlets can also be discerned along the length of this rille, possibly caused by a collapse of an underlying structure.This 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 crater s.atellite craters
By convention these features are identified on lunar maps by placing the letter on the side of the crater mid-point that is closest to Hyginus crater.
