According to General Relativity, as distinct from Newtonian gravity, motion under gravity is treated by a theory that deals, initially, only with same time, satellite measurements deal with extended bodies.

Being possibly mean density orbiting body in the Solar system, this satellite provides the best realization of a test particle ever reached experimentally and provides possibility for testing the predictions of General Relativity.

Abstract
According to General Relativity, as distinct from Newtonian gravity, motion under gravity is treated by a theory that deals, initially, only with same time, satellite measurements deal with extended bodies. We discuss the correspondence between geodesic motion in General Relativity and extended body by means of the Ehlers-Geroch theorem, and in the context of the recently launched LAser RElativity Satellite (LARES). Being possibly mean density orbiting body in the Solar system, this satellite provides the best realization of a test particle ever reached experimentally and provides possibility for testing the predictions of General Relativity.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
