Planet X myth debunked

It was an elusive planet that for 200 years appeared to explain Uranus‘s wobbly orbit. And there was the sister sun theorized to be near our solar system that caused asteroids to swerve toward Earth.

There is just one problem: neitherPlanet XnorNemesisever existed, researchers now say.

Or probably not.

The outer solar system probably does not contain a large gas giant planet (“Planet X”), or a small, companion star (“Nemesis”),” concluded University of Pennsylvania astronomer Kevin Luhman, who directed the study using NASA’s Wide-field Infrared Survey Explorer (WISE) telescope.


Most theories had estimated Planet X to be up to four times the size of Jupiterthe biggest planet in our solar system.

They suggested it would be found some 1,486 kilomita bilioni (923 bilioni maili) from the sun, au juu ya 10,000 times farther than the Earth’s orbit.

History of Planet X

Attempts to track this mysterious Planet X led to the discovery of Neptune in 1846. But the estimated mass of Neptune couldn’t explain the deviations of Uranus’s orbit.

That led astronomers to continue their search for Planet X — ambayo, kwa upande, led to the discovery of Pluto in 1930. But the dwarf planet was also too small to explain Uranus’s irregular path around the sun.

hatimaye, in the 1990s, researchers determined that they had slightly overestimated the mass of Neptune, which meant the planet could in fact be the reason for Uranus’s orbital behavior.

Yet Planet X believers were still not convinced.

Collisions like these are blamed for the five mass extinctions over the last 540 million yearsthe most recent being the dinosaur extinction 65 miaka milioni iliyopita.


But the WISE telescope didn’t find anything.

The hunt for Planet X and Nemesis may have turned up empty, but the study did uncover 3,525 stars and brown dwarfscelestial objects whose mass puts them between a star and a large planetwithin 500 light years of the sun.

Neighboring star systems that have been hiding in plain sight just jump out in the WISE data,” said Ned Wright, a Chuo Kikuu cha California, Los Angeles astronomer who contributed to the study.
