Strange young super-Jupiter challenges theories of planet formation

A newly discovered planet has the diameter of Jupiter only eight times its mass, giving it twice the density of Earth, despite being mostly gas. Not only have these features of this “super Jupiter” baffled astronomers, but they may also call into question current theories of planet formation.

The exoplanetwhich is about 310 light-years outside the solar system in the constellation Centaurus, orbits on a sun-like orbit star and is only 15 million years old, making it a relative baby in cosmic terms and compared to our 4.6 billion year old planet. A team of astronomers was able to measure both the diameter and mass of this gas giant – dubbed a “super Jupiter” because it is more massive than its solar system namesake – making it the youngest planet of its kind to ever receive such measurements. to be executed. created.
