Nibiru? Solar system may have Planet X & Planet Y

 

Scientists have postulated the existence

of possibly two undiscovered planets beyond the orbit of Neptune to

explain discrepancies in the orbits of extreme trans-Neptunian objects

(ETNO). The objects have orbits that take them beyond the orbit of the

planet Neptune.

Theory predicts that they be randomly distributed and that their

orbits must have a semi-major axis with a value around 150 AU; an

orbital inclination of nearly zero degrees; and an angle of perihelion,

the point in the object’s orbit at which it is closest to the Sun, of

zero to 180 degrees.

However, a dozen ETNO do not fit these orbital criteria. These

objects have semi-major axis values of 150 to 525 AU, orbital

inclinations of around 20 degrees, and angles of perihelion far from 180

degrees.

According to a statement,

a new study by astrophysicists at the Complutense University of Madrid

(UCM) and University of Cambridge have calculated that these orbital

discrepancies could be explained by the existence of at least two

additional planets beyond the orbits of Neptune and dwarf planet Pluto.

Their study suggests that the gravitational pulls of those two planets

must be disturbing the orbits of some smaller ETNO.

However, there are two difficulties with the hypothesis. One is that

current models of the formation of our solar system do not allow for

additional planets beyond Neptune. Secondly, the team’s sample size is

very small, only 13 objects. However, additional results are in the

pipeline, which will expand the sample.

“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,” said Carlos de la Fuente Marcos of UCM and lead author on the

study.

The new findings have been published in two papers published in the

journal Monthly Notices of the Royal Astronomical Society Letters.
