planetarity

Planetarity refers to the characteristic of a surface, like a planetary body's landscape, that exhibits continuous curvature, resembling a sphere or a planet. It describes how the terrain's shape is predominantly curved rather than flat or irregular. This concept helps scientists understand large-scale geological features and how they conform to the overall roundness of celestial bodies. Essentially, planetarity captures the idea that the surface undulates smoothly, emphasizing the spherical or rounded nature of planetary terrains, making it a useful measure in planetary geology and geomorphology.
