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.
The hypothetical planet - four times the size of Earth - will float beyond Neptune and Pluto and cause disturbances in the Kuiper belt of asteroids
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.
