The Nice Model of Planetary Formation Poster

Learn about the leading theories that explain the formation of our solar system with this poster, exclusively from Astronomy magazine.

About 4.6 billion years ago, a dense cloud of interstellar gas and dust collapsed into a stellar nebula. In the center of this swirling disk our star was born. While the Sun continued to amass material, clumps of matter further out in the disk slammed into each other, forming the planets. But astronomers don’t think the planets have always been at their current distances from the Sun and a few leading theories explain their migration.  Learn more about the Grand Tack and Nice models in this poster about solar system formation.
