If there is a black hole, it's at least 20 times farther from Earth than the furthest planet, Neptune, in a distant region of our solar system called the extended Kuiper Belt.

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.

If microscopic black holes born a fraction of a second after the Big Bang exist, then at least one may fly through the solar system per decade, generating tiny gravitational distortions.

A new theory suggests that a so-called primordial black hole may lurk beyond Neptune in the outer solar system. IE 11 is not supported. For an optimal experience visit our site on another browser.
