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

The solar system could be destroyed much sooner than we thought, scientists say - Outer planets could be thrown out into the ...

A new study published in The Astrophysical Journal Letters suggests that the outer solar system could become dynamically unstable about one billion years after the Sun becomes a white dwarf, ...

According to a new study, the Solar System may break apart within about 6 billion years as the dying Sun’s uneven mass loss destabilizes the outer planets.

An international team of astronomers has discovered eight new extrasolar planets, bringing to nearly 80 the number of planets found orbiting nearby stars. The latest discoveries, supported by the ...

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 ...

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, ...

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 ...

In 2015, NASA’s Kepler Space Telescope identified one of the most Earth like planets ever discovered, Kepler 452b. It orbits ...

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, ...
