Jupiter, the largest planet in the solar system, was 2 to 2.5 times bigger in its earlier life, according to new research. Jupiter, the largest planet orbiting the sun, used to be much bigger and ...

Illustration comparing the planets of the Solar System and the Sun on the same scale. The planets are shown to scale relative to each other but their distances are not. From left to right the bodies ...

Once thought to be the debris of a destroyed planet, the asteroid belt is now understood as a region shaped by gravity, collisions and the powerful influence of Jupiter. Studying it helps scientists ...

Simulations reveal that Jupiter’s rapid growth disrupted the early solar system, creating rings where new planetesimals formed much later than expected. These late-forming bodies match the ages and ...

A new scientific study suggests that Earth might not exist as we know it today if Jupiter were never around. Astronomers believe Jupiter’s strong gravity has helped keep our planet’s orbit safe and ...

A possible new dwarf planet has been discovered at the edge of our solar system, so far-flung that it takes around 25,000 years to complete one orbit around the sun. The object, known as 2017 OF201, ...
