The following thesis analyses deep-space data recorded by the Voyager 1 and Voyager 2 probes, covering the period between January 1, 2016, and December 31, 2020. These data were collected at distances ranging from 133.57 to 151.41 astronomical units (AU) for Voyager 1 and from 109.98 to 125.83 AU for Voyager 2. The data were provided by NASA's @Omniweb database and include information on the magnetic field in its three components and magnitude, as well as data related to three proton parameters, as velocity, density, and temperature, when available. Based on the available data, the investigation aims to contribute to predicting the future trends, with the goal of identifying the positions of the probes within the Interstellar Medium.
