Quote:At least two planets comparable to the Earth in size may be hovering at the Solar System’s edge. This discovery is likely to revolutionize our understanding of the Universe.
Scientists have spent decades arguing whether any yet undiscovered planet is hiding beyond the dwarf planet Pluto, and it seems the optimists have got the upper hand.
Astronomers were scrutinizing the motion trajectories of a belt of faraway space rocks, “ETNO – extreme trans-Neptunian objects”. They registered that their actual paths surprisingly contradicted the computer-simulated trajectories as if there was something heavy that pulled the observed celestial bodies with its gravity.
There is only one credible reason for this phenomenon, the astronomers concluded. “This excess of objects with unexpected orbital parameters makes us 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,” explains Carlos de la Fuente Marcos, the co-author of the research at the Complutense University of Madrid, as quoted by The Independent.
