Earth has a 1-in-500 (0.2 percent) chance that it will be lost due to either being ejected from the Solar System or colliding with another world.

Solar System – Jupiter. It is the fifth planet from the Sun and the largest in the Solar System. Its a giant planet with a mass one-thousandth that of the Sun. Elements of this image furnished by NASA ...

Heavenly questions China extends its reach into the Solar System with launch of asteroid mission Tianwen-2 will first return samples from an asteroid, then explore a mysterious comet-like object.

In the wake of Pluto’s reclassification, in 2016, Caltech astronomers Konstantin Batygin and Mike Brown proposed that an unknown Planet Nine might still exist in an orbit much further beyond Pluto in ...

Our solar system consists of four small, rocky, inner planets (Mercury, Venus, Earth and Mars) and four large, gaseous, outer planets (Jupiter, Saturn, Uranus and Neptune).

The Solar System’s closest approach to Radcliffe, researchers estimate, occurred around 14 million years ago. This journey may have altered the light of distant stars reaching Earth.

Primordial helium from the beginning of the solar system may be stuck inside Earth's solid core, new research suggests. The findings could have implications for a long-standing debate about how ...

A small percentage of the ejected objects — 0.03 percent — pass through our solar system, Gregg and Wiegert say, but none of the large bodies is close enough for telescopes to see.

As a result, the borders of our Solar System remain a bit of a mystery to scientists, even as we develop telescopes that can see light years away and deep into the cosmic past.
