If I remember right, Kepler's second law states that an object in an elliptical orbit covers equal areas in equal times. Since the area described by the sun-planet radius along path ABC is greater than the area associated with path CDA, that means T(ABC) > T(CDA). So I'd say proposition (1) is correct. · 1 year, 7 months ago
