Astronomer insists there is a Planet X four times the size of Earth lurking at the edge of our solar system

The evidence for ‘Planet X’ – the mysterious hypothesised planet on the edge of our solar system – has taken a new turn thanks to the mathematics of a noted astronomer.
Rodney Gomes, an astronomer at the National Observatory of Brazil in Rio de Janeiro, says the irregular orbits of small icy bodies beyond Neptune imply that a planet four times the size of Earth is swirling around our sun in the fringes of the solar system.
Planet X – perhaps mis-named now that Pluto has been demoted to a dwarf planet – has been widely hypothesised for decade, but has never been proven.
Gomes measured the orbits of 92 Kuiper belt objects – small bodies and dwarf planets – and said that six objects appeared to be tugged off-course compared to their expected orbits.
He told astronomers at the American Astronomical Society on Tuesday that the most likely reason for the irregular orbits was a ‘planetary-mass solar companion’ – a distant body of planet size that is powerful enough to move the Kuiper belt objects.
He suggested the planet would be four times bigger than Earth – around the size of Nepture and would be 140 billion miles from the sun, or about 1,500 times further than the Earth.
