DISCOVERY OF TWO NEW PLANETS IN SOLAR SYSTEM



Researchers counsel that "at least two" planets lie on the far side Pluto. Paris.  The system has a minimum of 2 a lot of planets waiting to be discovered on the far side the orbit of Pluto, Spanish and British astronomers say.
The official list of planets in our star system runs to eight, with superior planet Neptune the outer.
Beyond Neptune, Pluto was relegated to the standing of "dwarf planet" by the International Astronomical Union in 2006, though it's still championed by some because the most distant planet from the Sun.

In a study printed within the latest issue of a people journal Monthly Notices of the Royal Astronomical Society, researchers propose that "at least two" planets lie on the far side Pluto.
Their calculations area unit supported the bizarre orbital behavior of terribly distant area rocks known as extreme trans-Neptunian objects.

In theory, ETNOs ought to be spread in an exceedingly band some a hundred and fifty Astronomical Units (AU) from the Sun.

An AU, a measure of system distance, is that the span between Earth and therefore the Sun -- nearly a hundred and fifty million kilometers (almost ninety three million miles).
ETNOs ought to even be a lot of or less on an equivalent sheet because the system planets.
But observations of a couple of dozen ETNOs have recommended a quite totally different image, the study says.

If correct, they imply that ETNOs area unit scattered far more wide, at between a hundred and fifty and 525 AU, associated with an orbital inclination of regarding twenty degrees.
These terribly massive objects -- planets -- should be within the neighborhood and their attraction is bossing a lot of smaller ETNOs around.

The parameters makes United States believe that some invisible forces area unit neutering the distribution" of the ETNOs, aforementioned Glen Gerhard Delaware la Fuentes Marcos of the Completeness University of capital of Spain.

The information we've got is restricted, however our calculations counsel that there are a unit a minimum of 2 planets, and possibly a lot of, among the ambit of our system," the Spanish scientific news organization Sink quoted him as speech. "If it's confirmed, our results are also really revolutionary for natural philosophy." So far, there's no evidence to substantiate the speculation.
Marcos's team, which incorporates astrophysicists at the University of Cambridge, devised a model supported changes antecedently ascertained within the orbit of a extraterrestrial object known as 96P Machholz one once it came close to Jupiter, the largest planet within the system.
Based on this model, the movement of the ETNOs was in keeping with one planet at nearly two hundred AU and another at regarding 250 AU, they said.

Last year, the ALMA advanced telescope, situated in Chile's bone-dry Atacama Desert, found that planets in alternative star systems will type many AU from their sun.
Neptune orbits at a median distance of regarding thirty AU, and Pluto, that contains an extremely eccentric orbit, circles the Sun at a median of regarding forty AU.
