In 2006, the International Astronomical Union expelled Pluto from the title of the ninth largest planet in the solar system, and in the following ten years, Pluto once made a lot of noise, but in recent years, Pluto seems to have become accustomed to this leisure, sunrise and sunset.
At the same time, people's eyes are gradually shifting away from Pluto, but recently, the Hubble Space Telescope in the United States has detected an unusual gravitational disturbance at the edge of the solar system.
This discovery brought the expulsed Planet Nine back to the world's attention, and some even thought that the gossip might really have something to do with Pluto.
After all, in 1950, the American astronomer Professor Randall discovered Pluto's strange gravitational disturbance when calculating Pluto's gravitational problem, and even suspected that Pluto's orbit was affected by an undiscovered planet.
After years of scientific research and exploration, some scientists really believe that there is still an undiscovered planet in the solar system, and there are more than ten years when Pluto is difficult to calm down.
And now, such an anomalous gravitational disturbance has reappeared, so is this abnormal gravitational pull Pluto's "revenge" or really subverting our cognition?
Do "monsters" really exist?
Abnormal gravitational attraction occurs.
When the Hubble Space Telescope in the United States was observing small objects around the solar system, it found that the movement of the marginal asteroids appeared to be abnormal.
In the results of the calculations, the trajectory of these marginal asteroids is relatively close to the Sun, and the asteroids show a tendency to change outward, and vice versa.
For such a result, astronomers quickly understood the reason after analysis, that is, under the action of the sun's gravitational pull, the trajectory of these asteroids should indeed show such a "spiral" shape.
However, when they compared the orbits of these asteroids in different orbits, they found that the movement trends of asteroids in different positions are indeed very different.
In other words, at the edge of the solar system, the asteroids move in a significantly different trend than the asteroids in the inner solar system, so astronomers made further observations of this particular phenomenon, and finally found the strange gravitational escape of the marginal asteroids in the data of the Hubble telescope.
This abnormal gravitational pull clearly invokes the edge of the solar system, and if we look at the previous interpretation, the edge of the solar system was originally the range that the sun's gravitational force could cover, so the edge of the solar system would not have had any gravitational disturbances.
The anomalous performance, which had never been seen before, immediately attracted the attention of astronomers.
For Pluto, it has long since faded out of the world's sight at this time, but it is like a star hanging in the sky, not so much that it has returned to the stage of the solar system, but that it stands in the center of the stage.
People have come up with various theories about the ninth planet, and the abnormal gravitational disturbance at the edge of the solar system may be caused by the wandering black hole of the spacecraft, and some people believe that this may really be the revenge of Pluto, which originally belonged to the ninth planet of the solar system.
Prior to this, some people also thought that Pluto was a "moon" at the edge of the solar system, and that Pluto's own mass was not very small, so it may be more like the ninth planet in essence, after all, Pluto was not deducted from the classification of this planet when it was originally classified.
However, according to the Hubble Astronomical Telescope's observation of objects at the edge of the solar system, the gravitational pull of this anomalous center of gravity is about 640 times that of the Sun, a figure far from Pluto.
