Computer simulations have revealed a plausible explanation for a phenomenon that has puzzled astronomers: Rather than occupying orbits at regular distances from a star, giant gas planets similar to ...

Scientists have been trying to find a hypothetical Planet 9 that may exist outside our known solar system based on the unusual orbits of certain dwarf planets. But those orbits might not require a ...

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

Theorbits of Jupiter, Saturn, Uranus and Neptune may have been altered by the fly-by of an enormous object from deep space, billions of years ago. According to a pre-print research paper, which is yet ...

Astronomers have reportedly discovered a skyscraper-sized asteroid moving through our solar system at a near record-breaking pace. The asteroid, named 2025 SC79, circles the sun once every 128 days, ...

Astronomers have discovered a rare in-sync solar system with six planets moving like a grand cosmic orchestra, untouched by outside forces since their birth billions of years ago. The find, announced ...
