The Solar System's biggest moons
Most planets in our solar system are accompanied by at least one moon. You now wonder which planets are circled by the biggest moons and want to create a top five based on moon radius. However, you'll first have to unnest the devstronomy project data in planet_df using the unnest_longer() and unnest_wider() functions.
The dplyr package has been pre-loaded for you.
