A planet or primordial black hole in the outer region of the Solar system and the dust flow near Earth orbit

Abstract

In recent years, evidence has been obtained that in the outer region of the Solar System (in the inner part of the Oort cloud), at a distance $\sim 300-700$ AU from the Sun, there may be a captured planet or a primordial black hole. In this paper, we show that the gravitational scattering of dust particles in the same region on this object can transfer them to new elongated orbits reaching the Earth's orbit. With the mass of the captured object of the order of 5-10 Earth masses, the calculated dust flow near the Earth $\sim 0.1-3$$\mu$g m${}^{-2}$ yr${}^{-1}$ is comparable in order of magnitude with the observed flow. This effect gives a joint restriction on the parameters of the captured object and on the amount of dust in the Oort cloud.
