Strange young super-Jupiter challenges planetary training theories

A newly discovered planet is Jupiter’s diameter but eight times the mass, giving it twice the density of Earth, despite being mostly gas. These properties of this “super Jupiter” have not only puzzled astronomers, but may challenge current theories of planet formation.

tea exoplanetwhich lies about 310 light-years out solar system in the constellation Centaurus, orbits a sun-like one star and is only 15 million years old, making it a relative infant in cosmic terms and compared to our 4.6 billion year old planet. A team of astronomers has been able to measure both the diameter and mass of this gas giant – dubbed “SuperJupiter” because it is more massive than its namesake in the Solar System – making it the youngest planet of its kind to be known ever such measurements were made.
