SUMMARY
The discussion focuses on calculating the orbital period of a planet with a perihelion distance of 2.00 astronomical units (a.u.) and an eccentricity of 0.5000. The user applies Kepler's Third Law, stating that the square of the period (T) is proportional to the cube of the semi-major axis (a). After deriving the semi-major axis as 4.00 a.u., the user calculates the period T as 8 years, confirming the application of the formula T² = a³ is correct. The final conclusion is that the orbital period of the planet is indeed 8 years.
