- Аннотация: The structure of spacetime near a wormhole (WH) and possible observational consequences areinvestigated theoretically. In connection with the growing accuracy of observations and the prospects of a newgravitational-wave channel, the problem of distinguishing between astrophysical manifestations of blackholes (BHs) and hypothetical WHs is becoming relevant. WHs, along with BHs, naturally arise within generalrelativity (GR). Observational searches for WHs require knowledge of the characteristic trajectories of bodiesin its vicinity, including the trajectories entering its throat. Equations of motion of a test particle in the WHmetric are derived, and the most interesting properties of these motions are considered. A general equationof geodesics in the WH metric is derived, and some properties of these geodesics are considered. The exactsolution for circular orbits of test particles around a WH, as well as an approximate analytical solution of thegeodesic equations, is analyzed. The shift of the pericenter of the orbit of a test particle in the WH field is considered,and possible observational consequences are discussed. Examples of test particle trajectories near aWH are presented that are obtained by numerical simulation.
