As planetary systems evolve, gravitational interactions between planets can fling some of them into eccentric elliptical orbits around the host star, or even out of the system altogether. Smaller ...

New simulations examine whether the seven planets in the TRAPPIST-1 system could host moons, showing that only small, close-orbiting moons could remain stable over long periods ...

As planetary systems evolve, gravitational interactions between planets can fling some of them into eccentric elliptical orbits around the host star. Smaller planets should be more susceptible to this ...

Scientists have a new explanation for the mystery of why some alien planets the size of Jupiter or larger travel in the opposite direction of their parent star's spin. Of the more than 500 alien ...

Some zones encircling baby stars are far more popular than others, drawing crowds of giant planets while the other potential paths for orbits remain empty.Now computer simulations may reveal why, ...

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 ...
