At least two Earth - sized planets may be hidden on the edge of our solar system, an astronomer has said.Prof Carlos de la Fuente Marcos’s study of rocks beyond Neptune and dwarf planet Pluto showed “invisible forces” affect their orbits. He said: “The most probable explanation is that unknown planets exist.
“The exact number is uncertain but our calculations suggest there are at least two, probably more. ”
If the results are confirmed it “may be revolutionary for astronomy”, he said. The Madrid university professor’s study looked at rocks known as extreme trans - Neptunion objects. The findings are published in journal Monthly Notices of the Royal Astronomical Society Letters.SEE ALSO:NASA probe wakes up in anticipation of rendezvous with PlutoAt least two as - yet undiscovered planets as big as Earth or larger may be hiding in the outer fringes of the Solar System, scientists believe. The secret worlds are thought to exist beyond the orbits of Neptune, the furthest true planet from the Sun, and the even more distant tiny “dwarf planet” Pluto. The evidence comes from observations of a belt of space rocks known as “extreme trans - Neptunion objects”(Etnos). Orbiting the Sun beyond Neptune, Etnos should be distributed randomly with paths that have certain defined characteristics. But a dozen of the bodies have completely unexpected orbital values consistent with them being influenced by the gravitational pull of something unseen. Astronomers have spent decades debating whether a hidden planet beyond Pluto remained undiscovered.SEE ALSO:Mars colonization project marred by radiation, gravity fears Reference:
