In 2016, many astronomers pointed to a large source of gravity in deep solar space, saying it was possible. But the new article explains that the source of gravity could be nothing but the statistical mirage, the result of where astronomers point their telescopes in the night sky. The first physical (CK) clue of this hypothetical Planet Nine was a group of space rocks with similar orbits that seem unusually close to each other. These faint, distant, hard-to-view objects orbit away from Neptune and are known as “trans-Neptune objects” (TNOs).
Because the distant and cold little planets in the solar system reflect very little sunlight, they tend to blend into the much brighter background of stars and galaxies that make most astronomers wonder, and only a handful have been identified and cataloged so far. (The most famous of these is the reduced dwarf planet Pluto orbiting relatively close to the sun compared to many of its TNO cousins.)
But in 2016, astronomers Konstantin Batygin and Mike Brown from the California Institute of Technology saw that all six TNOs, including the dwarf planet Sedna, had long elliptical and “eccentric” orbits oriented in the same direction. Eccentric here means that its opiums or a distant point is much further away from the sun than the perihelion or points closest to the sun. And all six had opiums on almost the same side of the solar system. In a 2016 article published in The Astronomical Journal, Batygin and Brown wrote that by following a long elliptical path around the Sun, a planet much farther away from Pluto, about 10 times the mass of Earth, could explain the apparent cluster. They said that over time, great gravity would pull these six TNOs into their clustered orbits.
But in this new article published in the arXiv database on February 12, but not yet peer-reviewed, a large collaboration of researchers suggests that TNOs are not particularly clustered – it just seemed to be because of where Humans were directing their telescopes. . The researchers took a sample of 14 known “extreme” TNOs (belonging to the family of objects that orbit the Planet Nine most, orbiting very distantly) and assumed that the samples were part of a much larger family of objects, mostly invisible. has. Then they analyzed how much time telescopes spent pointing to different parts of the sky. They found that if all TNOs at the outermost edges of the solar system could actually have a fairly uniform distribution, astronomers could detect this particular collection of objects – between 17% and 94% uniform everywhere. (A 100% uniform distribution means that the TNO orbits are evenly spaced around the sun.) In other words, excess TNOs (ETNOs) may appear to be clustered, but only because telescopes have focused their attention on it on average. part of space. Such a uniform distribution does not fit the Nine Planets hypothesis.
