The Wall of Time

The development of our solar system can be viewed as a continuous and complicated process that started about 4.6 billion years ago. As scientists continue to study the solar system, and Earth in particular, their understanding of the sequence of events that led to the planetary conditions we see today continues to gain detail and clarity. This illustrated timeline from the Lunar and Planetary Institute shows major milestones in the development of the solar system and Earth.
