The search for life beyond Earth is a holy grail quest for many experts, but finding where to look is a core issue.

But considering that this object, if it does exist, causes only tiny irregularities in the solar system's planets, a primordial black hole far out in the solar system wouldn't have very big effects.

If our sun were replaced with a black hole of the same mass, our solar system would orbit similarly to how it does now, but it would be a lot colder. We don’t know what matter looks like inside ...

Objects in the solar system orbit pretty close to the same plane that the planets orbit in, and all at speeds low enough to keep them bound in the Sun’s gravitational field.

Our Solar System is full of mysteries, but if the inner planets are a puzzle, the boundary between the Solar System and interstellar space is a secondhand puzzle with half the pieces missing.

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 ).

Astronomers have revealed new research showing that millions of new solar system objects are likely to be detected by a brand-new facility, which is expected to come online later this year.

Instead, they say that if primordial black holes exist and make up most of dark matter, "then one must travel through the inner solar system every one to 10 years." ...

This process, called accretion, is how everything in the solar system – planets, moons, comets and asteroids – came into being. Telescopes can see young solar systems being born.
