Astronomical physics suggests a new place to hide for the nine planets

Planet Nine, in the artist's imagination.

Five years ago, two astronomers To announce They have discovered evidence of another planet in our solar system called “Planet X”. Although it is now called Planet Nine, the cosmic body – much larger than Earth and lurking somewhere outside the Solar System – is more theoretical, although the pair have their own possible orbit. This planet.

The new research comes from Mike Brown and Constantine Patigin of the California Institute of Technology. Brown “kills and is proud of Pluto”, Kismodo Described in 2016. Currently being conducted The preprint server has been approved for publication in arXiv and The Astrophysical Journal, research says that if Planet Nine is closer and brighter than previously thought.

Scientists suspect that there is an unknown planet based on the dense collection of objects in the Khyber belt, a large collection of ice bodies outside the orbit of Neptune. If an unnoticed planet lurks outside the belt, it will be the farthest orbit of all the planets around the sun, and it will take thousands of years to make a revolution.

Just as Neptune discovered when Uranus was being pulled by an invisible object in the 1840s, a number of Khyber belt objects appear in clusters in the same direction in space – this may be a random event, but some astronomers have not found the cause.

Other ideas have been suggested. Some Do you have a suggestion Planet Nine is actually a ring of debris large enough to cause gravitational effects like a giant planet, others suspect. Planet Nine is a primitive black holeTheoretical remnants of the early universe are too small to be detected by modern methods. Still others say there is no such thing.

Michael Bunnister, a planetary astronomer at the University of Canterbury in New Zealand, told Kismodo. 2017 “Planet 9 is a good idea, it’s exciting, but it’s taking a little oxygen right now,” and “We have an interesting problem … now the obvious solution is called Planet 9.”

New research has been very selective in selecting the added kyber belt materials to determine the mass, orbit and gravity of Planet Nine. Some objects in the belt have orbits affected by Neptune’s gravitational pull, which can distort their aggregation data. The final set of items – 11 in total – was selected based on the researchers’ strict criteria. Based on their analysis, the nine planets are 6 times larger than Earth and orbit the Sun once every 7,400 years. Like National Geographic reports.

A rock in space, the object of the Khyber belt, 4 billion miles from the sun.

The researchers also calculated the possibility of the orbital assembly being influenced by something other than a large object. They determined that there was a 99.6% chance of handling an object in the orbit of the Khyber belt. While this is a small opportunity, it is actually a huge increase (1 in 250) from the 10,000 discrepancies the pair released in 2016.

At the time, Brown and Body believed that the planet was too large (10 times the mass of Earth) and that its orbit was too long. 10000 years) Than described in the new article. Their new estimate is that the nine planets must be close to the sun – close enough that, in fact, this can be observed. Vera Rubin-Observatory, Is expected The first light in 2023.
