WebThe Principal Axis (PA) system is a lunar body-fixed rotating coordinate system whose axes are defined by the principal axes of the Moon. Due to the fact that the Moon is not truly a synchronously rotating triaxial ellipsoid, the PA and ME rotation axes do not coincide. The axes of the two systems differ by about 1 km at the lunar surface. WebRigid-body rotation can be broken into the following two classifications. 1) Rotation about a fixed axis: A body can be constrained to rotate about an axis that has a fixed location …
