Geophysical Planet Definition (GPD) Users Page

The Geophysical Planet Definition (or GPD) can be stated as “A planet is a sub-stellar mass body that has never undergone nuclear fusion and that has enough gravitation to be round due to hydrostatic equilibrium regardless of its orbital parameters.”

We are sampling community usage in GPD. Specifically, we want to know if you as a planetary scientist think that the GPD is a useful planet definition (recognizing that other planet definition may also be useful to you). To that end we’ve developed a form at:

for those who find GPD a handy definition and who want to help us gauge that interest.
