New research has uncovered as many as 10 new candidates, while proving that the candidate for the location of the ninth planet in the solar system is not a planet.
The project, led by astronomer Sigurd Naess at the Flatiron Institute’s Center for Computational Astrophysics, used the 6-meter Atacama Space Telescope in Chile to survey remote areas. . . of the solar system. Sky.
The telescope is designed to detect the faintest signals left by the Big Bang, but is also sensitive enough to detect objects in the far reaches of the solar system.
Between 2013 and 2019, the telescope scanned about 87 percent of the southern sky at a distance of 300 to 2,000 AU.
The search has yielded an expected 3,500 candidates, according to Science Alert. They then screened the 10 most promising Planet 9 candidates, which will be the target of more detailed studies in the future.
However, the survey also ruled out another good candidate, which the study predicted could be the previous ninth planet.
Although no planet 9 has been confirmed so far, the search for it has uncovered many interesting objects on the other side of the solar system, such as asteroids. When planets like Earth hadn’t formed, something ancient was carrying basic matter.
While yet to be discovered, scientists have repeatedly found signs that distant space rocks are being affected by something — whether it’s a small black hole or a giant planet.
If anything, the ninth planet would have to be 5 to 10 times larger than Earth and take 10,000 to 20,000 years to orbit the sun.
The research has just been published in The Astrophysical Journal.
