Zsigmondy (crater) Zsigmondy is a lunar crater located beyond the northwestern limb on the far side of the Moon. Attached to the southeastern rim of the crater is the crater Omar Khayyam, which lies within the much larger Poczobutt. Farther to the east, along the north rim of Poczobutt, is Smoluchowski.
Barycenter The barycenter (or barycentre; from the Ancient Greek βαρύς "heavy" + κέντρον "centre") is the center of mass of two or more bodies that are orbiting each other, which is the point around which they both orbit. It is an important concept in fields such as astronomy and astrophysics. The distance from a body's center of mass to the barycenter can be calculated as a simple two-body problem.
