What is the primary focus of the proposed geophysical definition for a planet?
Answer
The body's intrinsic physical state: being rounded by gravity but not initiating core nuclear fusion
The geophysical view suggests an object should be classified as a planet based purely on its physical properties—specifically, being massive enough to be spherical due to gravity but not massive enough to begin nuclear fusion, making environment secondary.
