Jack Lissauer System Quotations

The solar system is not a stable and quiet place.

Long-term changes to the system include collisions and crossing ring systems.

The destruction and accumulation of moons and rings is very exciting. It's showing how this system is very rapidly evolving and showing that the processes which led to the formation of the planets (are) still ongoing today.

Now we're realizing that planetary systems are continually evolving. They change at a slower rate as they get older, but they continue to change.
