a long enough astrophysics to study the theory of "the ninth planet," according to which on the outskirts of our Solar system there is a mysterious heavenly body and it is impossible to detect. Scientists at Harvard University made a surprising assumption: in their view, remote from the Sun orbit might be not a planet, but a tiny black hole. Based on what this hypothesis does black hole potential threat to mankind – in the column browser, Nikolay Grinko. The conclusion about the possible existence of "the ninth planet" is made based on the study of orbits of TRANS-Neptunian objects. Scientists have even calculated the approximate characteristics of a celestial body: it must weigh several times more than the Earth and revolve around the Sun in about 15 thousand earth years. But for the time of the observation space, the planet was never found.

Recently astrophysicists are getting more data from remote regions of the Solar system, many of the parameters suggests that somewhere there must be a large object. And it’s very strange, because the massive planet illuminated by the Sun must be visible, just like everyone else.

These facts led scientists to believe that the mysterious object can be very compact black hole. Its mass can exceed the earth’s five to ten times. In this case it is about the size of a large egg. The existence of such black holes predicted by Stephen Hawking and other researchers who called them primordial black holes. According to some calculations, the Universe may be a huge amount. To detect "primordial black hole" can only by circumstantial evidence: its impact on the movement of other objects or bright flashes that appear when, for example, hole absorbs her passing near the comet. But such events are incredibly rare, and the biggest difficulty is that you need to know exactly where to look, and we don’t know that. But there is another way: to continually scan the surrounding space at high resolution. Scientists have proposed to start building a new telescope that will take pictures of the entire night sky every few days to detect spontaneous flashes from primordial black hole. The project is called LSST (Legacy Survey of Space and Time). Its goal is the observation of the movement of objects, changes in their brightness and registration of short-term phenomena such as supernova explosions. It is expected that the telescope will be launched in 2023 and approximately ten years of experience can detect more than 40 thousand of new facilities on the outskirts of the Solar system. If, however, the mysterious ninth planet will be ultracompact black hole, it will explain many of the inconsistencies in having��Xia observations. But scientists have started from scratch to rewrite the existing model of astrophysics and cosmology, because all this is very bad fit in the existing theory.

However, for ordinary people the possible opening will not have too big consequences, and to expect any trouble from "the black hole next door" not worth it in the end, she has been there for 4.5 billion years without any incidents, so that in the foreseeable future nothing bad will happen.
