After Pluto was officially no longer considered a planet officially in the Solar system has only 8 planets — mercury, Venus, Earth, Mars , Saturn, Uranus and Neptune. However, a few years ago, astronomers reported the strange discovery: they had identified entirely new classes of objects, including a mysterious orbits, which are difficult to explain. According to them, all these asteroids and comets are moving this way for a reason: all because beyond Neptune is hiding a giant planet, which is far beyond what we see. However, most scientists have so far failed to convince its existence. Why? Apparently, the ninth planet just no.
A New study by astronomers at the University of Pennsylvania, calls into question the existence of the ninth planet, says New Scientist. 2014 scientists have tried to find an explanation for the strange behavior of small celestial bodies that revolve around our star beyond Neptune. They argued that these comic objects can influence the mass of which is five times the mass of the Earth. Others have come to the conclusion that the ninth planet — just a cluster of asteroids, comets and other small celestial bodies.
In the Solar system 8 planets now documented
Now, However, scientists analyzed data collected by a visual and infrared survey conducted in the Observatory in Chile. They found no evidence of accumulation of any "unusual TRANS-Neptunian objects" — of celestial bodies beyond Neptune.
According to our data, the existence of the ninth planet has become even more unlikely, but considering the studies of other scientists, the hope, albeit very little, but remains — said astronomer from the University of Pennsylvania.
This scientist led the other study, published in March, stating that he found 139 space objects in the Solar system. However these heavenly bodies are too small to be considered a "proper planet".
As soon as we find more distant objects, their distribution becomes more uniform. Any anomalies there.
Astronomers from Colorado do believe that most of the models that are used for tracking thousands of TRANS-Neptunian objects, to reduce the necessary computing power do not consider a lot of these objects. In other words, all these models represent a simplified picture of the real situation. And because these objects are not influenced by the gravity of Neptune, due to its own gravity they can form clusters.
According to another hypothesis, the isolation of the orbits of some TRANS-Neptunian objects can be explained by the asteroid collision, and not the gravitational influence of a hypothetical ninth planet.
Someone actually believes that the ninth planet — just a black hole
At the same time, the scientists say that in order to be sure that the ninth planet does not exist, you need to search every square kilometer of the Solar system, and make it very difficult. It took several thousand years before we understand how the planets revolve around the Sun, and hundreds before we discovered Uranus and Neptune. So if the ninth planet exists, it will find, perhaps, only by the end of this century.
However, supporters of the hypothesis about the existence of a ninth planet still believe and hope. According to them, astronomers simply do not have enough data to find the object. Supposedly, the unusual orbits of TRANS-Neptunian objects lead them too far from the Sun, where they become incredibly difficult to detect.
I think if the ninth planet actually existed, for so many years it could find. Scientists using telescopes (that's trillions of kilometres) and clearly would be able to find an object that is 5 times bigger than Earth. Now, astronomers basically are looking for such facilities by the transit method (a method of detecting exoplanets, based on observations of the passage of the planet on background stars), and if the ninth planet has a orbit, she would have already passed in the Sun. How do you think the theory of the ninth planet has a chance at life? Share in the comments and .
According to proponents of the ninth planet, it looks that way
