Scientists at Harvard University in the United States began to develop a method to detect black holes in the outer regions of the Solar system that will help to determine the nature of a hypothetical object, called planet X. this was reported in an article published in the ArXiv repository.
According to the researchers, if black hole close to Earth really exists, then it is possible to identify accretion outbursts that occur when comets from the Oort cloud fall into the gravitational field of the exotic object, and torn apart by tidal forces. At the same time they heat up due to friction of the flow of gas orbiting the black hole and emit radiation. These flashes can be detected by ground-based astronomical instruments in the framework of the project Legacy Survey of Space and Time in the Observatory named Vera Rubin in Chile, which will start at approximately 2022.
The method allows to detect small black holes of planetary mass or exclude their existence to the limits of the Oort Cloud, which covers about one hundred thousand astronomical units.
Earlier, in 2019, an international group of physicists from the UK and the USA suggested that the ninth planet of the Solar system, or planet X, is actually primary a black hole the size of a tennis ball or a bowling ball.
Scientists believe that one of the primary black holes in the milky Way does not have to be rare, could be captured by the Solar system. Since the appearance of Planet X is also due to the seizure (in this case the planet-wanderer), these events, according to the hypothesis, are equally likely.
