A study of the Beta Pictoris Moving Group (BPMG), a cluster of relatively young stars, suggests a high prevalence (20 out of 30 surveyed) of stars possessing Jupiter-mass planets in long-period orbits ...

Asteroid ‘Families’ Reveal Hidden Histories and Impact Risks across the Solar System ...

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 ...

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 ...

Scientists have long puzzled over why all of the planets in Earth’s solar system have slightly slanted orbits around the sun. But a new, Yale-led study suggests this phenomenon may not be so unusual ...

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 ...

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 ...

UNDATED (WKRC) - Astronomers recently made an important discovery when they found a rare "in-sync" solar system with six planets all moving in one big grand harmony, completely untouched by outside ...
