".. Jupiter formed only one million years after the beginning of the solar system as a rocky core, and the planet grew to about 20 Earth masses over the next million years. Over the course of an additional three to four million years, Jupiter's core grew to 50 Earth masses. The new study aligns with the prevailing theory that Jupiter formed as a rocky core and then accumulated large amounts of gas to become the giant planet we have today."
