Spanish researchers conducting a study on the utmost objects in the Solar System have uncovered new evidence to support the existence of an undiscovered massive remote planet in the Solar System .
It has been dubbedPlanet Nineand the first small-arm of evidence was how the orbits of trans - Neptunian objects ( TNOs ) are all distributed in certain directions . This was proposed by researchers at Caltech in January 2016 and several new bit of grounds have been lend since then . Another mathematical group of researcher working on TNOs observe some observational bias in their own body of work and suggested that the Planet Nine grounds found on TNOs needed to be curb again .
In a paper , published in theMonthly Notices of the Royal Astronomical Society : Letters , investigator from the University of Madrid have used a novel technique to study some of the most remote objects in the Solar System , aptly named utmost trans - Neptunian objects ( ETNOs ) .
ETNOs are at least 150 times further from the Sun than the Earth ( 150 Astronomical Units , 1 AU = distance from Earth to Sun ) and they do n’t cross Neptune ’s orbit . The team execute the good measurement to date of the nodes of the ETNOs . The nodes are the two stage where the range of a heavenly consistence crosses the plane of the Solar System . The nodes ' position mainly look on the size and contour of the orbit , which make them quite free from observation bias .
The squad study the nodes for 28 ETNOs and 24 small objects , known as Centaurs . They view that all the nodes appear to be allowed only in a sure chain of distances from the Sun and it they all come out to correlate , and there should n’t be any correlation .
" Assuming that the ETNOs are dynamically similar to the comet that interact with Jupiter , we render these results as signs of the front of a satellite that is actively interacting with them in a range of distances from 300 to 400 AU , " co - author Carlos de la Fuente Marcos said in astatement . " We believe that what we are see here can not be assign to the bearing of observational bias . "
The enquiry is in accord with the original research that suggests there ’s a monolithic object there , up to 10 times the deal of the Earth and expect to be about 600 to 700 AU from the Sun . The researchers will now face at the finding new evidence for the being ofPlanet Tena Mars - sizing physical object that should be locate much confining , only 50 AU aside .
