Astronomers found a strange planetary system 116 light-years away. It orbits a red dwarf star called LHS 1903. The planets are arranged in an unexpected order. The outermost planet is rocky, which ...

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 ...

For the inner four planets in this solar system, each planet orbits the sun three times for every two orbits of the planet immediately to its outside. For the fourth, fifth and sixth planets, they ...

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 ...

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 ...

The shape of a planet's orbit is one of its fundamental properties, along with its size and distance from its host star. Earth has a nearly circular orbit, but some planets outside our solar system, ...

EVANSTON, Ill. — Except for the fact that we call it home, for centuries astronomers didn’t have any particular reason to believe that our solar system was anything special in the universe. But, ...

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 ...
