One of the most curious questions about the solar system is whether there is a ninth planet lurking outside. In 2016, astronomers Mike Brown and Konstantin Battykin discovered that the orbits of some small celestial bodies in the Cooper Belt were very strange, which further strengthened the existence of Planet Nine, but they have not yet found clues. Recently, astronomers reviewed the data of infrared astronomical satellites in 1983 and accidentally discovered that there were 3 mysterious objects in it, which were actually the ninth planet.
In 1983, Michael Rowan-Robinson, an astronomer at Imperial College London, used the Infrared Astronomical Satellite (IRAS, the first infrared space telescope) to try to search for the imaginary 10th planet (Pluto was also listed in the solar system at the time). In the ninth planet), unfortunately, the result shows that the celestial body does not exist.
But because some small celestial bodies in the Cooper Belt have very strange trajectories, just like astronomers discovered that Uranus’s orbit is slightly different from mathematical predictions, and suspected that something was disturbing Uranus, and discovered Neptune in 1846. Some astrophysicists did this because of this. It is suspected that there may be a planet (or an object with extremely gravitational attraction, such as a primordial black hole) that will interfere with the celestial bodies in the Cooper Belt hidden in the periphery of the solar system.
This conjecture was further magnified in 2016. Astronomers Constantine Bettikin and Mike Brown from the California Institute of Technology used 6 extremely irregular orbital celestial bodies other than Pluto as the basis. They discovered through computer simulations that Planet Nine must Existence can explain them.
Recently, Michael Rowan-Robinson reviewed the infrared astronomical satellite data nearly 40 years ago. Unexpectedly, in June, July, and September of 1983, the data had 3 moving points in the sky. Although the detection quality of infrared astronomical satellites was very low. Modern instruments are lower in comparison, but Michael Rowan-Robinson claims that they are worth checking.
If Planet Nine is there, it will be 5 to 10 times larger than the Earth, and the distance between its orbit and the Sun is 800 times the Earth-Sun distance. This distance causes Planet Nine to appear very dark and only a small light can be seen. Point, or inferred by the influence of gravity on celestial bodies outside Neptune.
Of course, there are other theories that planet Nine is actually a circle of debris, or it may actually be a primordial black hole the size of a grapefruit.

The Vera Rubin Observatory in Chile is under construction. When it is completed, the telescope will use the largest digital camera in history that supports 3.2 billion pixels to photograph the entire sky. The resolution is equivalent to that one can be seen 25 kilometers away from the earth. A golf ball, a candle thousands of kilometers away, an object 100 million times darker than visible to the naked eye was found. People who are ready and willing to wait will always encounter opportunities…I hope we won’t have to wait too long.
The new paper will be published in the Monthly Notices of the Royal Astronomical Society, and the preprint can be viewed on the arXiv website.
