Knowing Jupiter's early spin also helped them calculate its size. By applying the physics rules of spinning objects, they figured out how big Jupiter had to have been to match that rotation.

Exoplanet TOI-778 b has a radius of 1.4 times that of Jupiter and is approximately 2.8 times more massive than the gas giant. TOI-778 b orbits its host every 4.6 days and has an estimated surface ...

Jupiter now appears 11-percent larger and more than one and a half times brighter than it did back in April 2017, ... That rapid rate of spinning gives Jupiter the look of a slightly flattened ball.

Researchers now appreciate that gas planets are more complex than first thought. New findings have implications for our ...

The meandering poles of Jupiter's moon Europa etched tell-tale scars across the satellite's icy surface, a new study finds. IE 11 is not supported.

Get Instant Summarized Text (Gist) Jupiter was about twice its current radius and possessed a magnetic field roughly 50 times stronger than today around 3.8 million years after the solar system's ...
