Scientists confirm that Jupiter is the oldest planet in the solar system
FirstpostJupiter - the largest planet in our solar system - is also the oldest, say scientists who found that the gas giant formed within four million years after the formation of the Sun. “Jupiter is the oldest planet of the solar system, and its solid core formed well before the solar nebula gas dissipated, consistent with the core accretion model for giant planet formation,” he said. Scientists showed through isotope analyses of meteorites that Jupiter’s solid core formed within only about one million years after the start of the solar system history, making it the oldest planet. The team found that Jupiter’s core grew to about 20 Earthmasses within one million years, followed by a more prolonged growth to 50 Earth masses until at least 3-4 million years after the solar system formed.
