The fate of our solar system is written in the stars—well, one star to be precise: the sun. Estimates of what the end will ...

The orbits of the planets around the sun have been the source for many a scientific debate. Their current orbital properties are well understood but the planetary orbits have evolved and changed since ...

New modeling shows that chaotic mass loss from the Sun could shake up the orbits of giant planets even before it turns into a ...

The Sun’s death is not an event the planets will quietly survive—it is the trigger for their orbital undoing.” ...

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, ...

Modelling suggests that the planets’ orbits will become destabilized inside one billion years once the Sun starts to shed ...

A new discovery finds that, even in “pristine” solar systems, planets exhibit a bit of a tilt. Scientists have long puzzled over why all of the planets in Earth’s solar system have slightly slanted ...

As published in The Astrophysical Journal Letters, theoretical astrophysicists Konstantin Batygin and Jim Fuller of Caltech, ...

Imagine if the planet Jupiter orbited much closer to the Sun. What effect would a so-called hot Jupiter have on our Solar ...

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, ...
