The ninth possible planet in the solar system, called Planet 9, has an orbit far beyond Neptune (shown as a ring around the sun). Tom Ruen.nagualdesign/ESO) The solar system has just become a bit strange. As astronomers continue to search for "elusive planet nine", a research team has discovered a space rock, which proves the idea that there is indeed a huge super-earth planet outside the solar system. "kdspe" and "kdsps" are newly discovered asteroids named 20 15 BP5 19. More and more evidence shows that the small world of the solar system is being disturbed by some big things. Astronomers describe its discovery and description in detail in a new paper, adding that the strange angle of its orbit makes the idea that a big planet is dragging an asteroid somewhere around the sun even more important.

"We also considered the' Planet Nine Hypothesis' and found that 20 15 BP5 19 increased the indirect evidence of the existence of new members in the solar system." Read the abstract of this article, which can now be found on the preprint website ARXIV and has been submitted to Astronomy Journal. How do astronomers really see' Planet 9'?

Following up on this discovery, Quantum magazine recently published an article and investigated several astrophysicists who specialize in the small world, including the discoverer of BP5 19 in 20 15. Although not everyone thinks that Planet 9 is the culprit of this strange orbit, most people think that this new discovery makes this idea more credible. Juliet Becker, the first author and a graduate student at the University of Michigan, told Total Tower magazine: "Put Planet 9 into the simulation for the second time, you can not only form an object like this, but also absolutely." .

This is not the first time that Planet Nine has been accused of pushing celestial bodies. As early as 20 14 years ago, before Planet 9 was formally assumed, astronomers Scott Sheppard and Chadwick Trujillo noticed that the orbits of several small celestial bodies outside Neptune's orbit were irregular. These include the dwarf planet Sedna, a newly discovered celestial body named 20 12 VP 1 13, and several other trans-Neptune celestial bodies (TNO).

Then, in June of 20 16 and 1 year, astronomers Konstantin Batikin and michael brown saw more evidence that TNO orbit was disturbed. They were the first people to give the ninth planet a name, size and distance. They think that this mysterious planet may be 10 times the mass of the earth and 600 astronomical units away from the sun. (An Au is the average distance from the earth to the sun, that is, 93 million miles or 654.38+0.5 million kilometers). "KDSP", "KDSP" and "KDSP" are the potential orbits of planet 9, which are illustrated by the existence orbits of several TNOS. (California Institute of Technology, R.Hurt/JPL)

A series of studies on the possible effects of tno and Planet 9 on their orbits; The following summary is just an example. Not all the teams are enthusiastic, and one team from the Investigation of the Origin of Extrasolar System (OSSOS) warned that many of these investigations may only be observation errors.

But astronomers insist that Shepard and trujillo have discovered at least two new TNOs that may be affected by the ninth planet. Another study shows that Planet 9 may have influenced the inclination of the planets in our solar system. In 20 17, astronomers at the university of Madrid in Spain found that the orbits of 22 "extreme" tnos around the sun were quite special, which can also be explained by the gravitational influence exerted by a huge and distant celestial body. (These TNOS have never been closer to the sun than Neptune-Neptune is 30 miles away from the sun and orbits the sun in a rough orbit, with an average distance of at least 150au. ) Batygin said that there are at least five different evidences for KDSP and KDSP, indicating that planets existed before 20 17 and 10. If you remove this explanation and imagine that the ninth planet does not exist, then you will create more problems than you solve. Suddenly, you have five different problems, and you have to come up with five different theories to explain them, "he said in a statement.
