A tiny black hole may pass through our solar system once every ten or so years, researchers have suggested, and this could be detected by watching Mars wobble.

But the black holes would have speeds of about 200 kilometers per second and come from outside the solar system. That’s rare for space rocks ( SN: 9/12/19 ).

The black hole that is the closest to our solar system has been discovered in our galactic backyard.. The local black hole is roughly 12 times the mass of our sun and is situated about 1,550 light ...

A diagram showing how distant solar system objects have aligned orbits, suggesting something else causing it. If the mystery object were a primordial black hole, however, it would be far smaller.

If a PBH found its way into our solar system, that black hole would orbit the sun like a planet would, and it would tug on dwarf planets and asteroids just like the theoretical Planet 9 would.
