Solar System appeared 4.6 billion years ago from the gravitational collapse of a giant interstellar molecular cloud. The vast bulk of the Solare system’s mass is in the Sun, with most of the remaining mass contained in Jupiter.

Pangea was a mega continent that existed throughout the late Paleozoic and early Mesozoic eras. It gathered from earlier continental parts about 335 million years ago, and it started to split apart about 175 million years ago.
