The Solar System is a fascinating place, with each planet orbiting the Sun at its own unique distance. But how far apart are these planets, and how do they travel through space? Uncover the true scale ...

Every decade or so, at least one microscopic black hole might be flying through our solar system, creating minuscule, detectable gravitational distortions. If astronomers can confirm the existence ...

A bowling ball-sized black hole of the outer reaches of the solar system is an outlandish theory, but at this point it's no less plausible than the existence of super Earth-sized planet.

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 that ...

In a study published Tuesday in the journal Physical Review D, physicists at MIT say the presence of a tiny black hole speeding through the solar system could be identified by the gentle ...

The first new planet in our solar system since the discovery of Neptune in 1846. Reporter: Very little is known about Neptune, the last of the giants on this tour. Narrator: But there was a problem.

Or cosmic rays." Planet 9 explains distant objects' weird orbits At the fringes of our solar system are thousands of small icy bodies that make up a region astronomers call the Kuiper Belt.

Ultimately, by 100 billion years after the Sun turns into a white dwarf, the Solar System is no more. That's a significantly shorter timeframe than that proposed in 1999.

It's not a cosmic vacuum cleaner." If a black hole did wander into our solar system, the largest effects would be gravitational. And those effects would depend on the mass of the black hole.

Astronomers are racing to explain peculiar orbits of faraway objects at the edge of our solar system. When you purchase through links on our site, we may earn an affiliate commission. Here’s how ...

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 ...
