• Co-author Carlos de la Fuente Marcos explained that this excess of objects with unexpected orbital parameters makes them believe that some invisible forces are altering the distribution of the orbital elements of the ETNO and we consider that the most probable explanation is that other unknown planets exist beyond Neptune and Pluto.
  • The exact number is uncertain, given that the data that we have is limited, but our calculations suggest that there are at least two planets, and probably more, within the confines of our solar system, adds the astrophysicist.
  • To carry out the study, the researchers have analysed the effects of the so-called ‘Kozai mechanism’, related to the gravitational perturbation that a large body exerts on the orbit of another much smaller and further away object.
