  1. A volcanic caldera
  2. A giant atmospheric storm ✔
  3. A gap in Jupiter's clouds

Why: The Great Red Spot is a rotating oval storm, not a surface feature. Jupiter lacks a solid surface, and its atmospheric vortices can persist for many years.

Huh, didn't know that: Juno gravity data constrain the storm to roughly 500 kilometers below the cloud tops.

The dad joke
Jupiter's spot has weathered centuries of weather.
