Favorite Answer. Customer Voice. While definitions based on altitude are inherently ambiguous, most of them fall within the range specified by an orbit period of 128 minutes because, according to Kepler's third law, this corresponds to a semi-major axis of 8,413 km (5,228 mi). Time it out for real assessment and get your results instantly. 23 hours, 56 Minutes and 4.1 seconds, yet it does NOT appear stationary from the earth. The period of the Earth as it travels around the sun is one year. ← Prev Question Next Question → Here the centripetal force is the gravitational force, and the axis mentioned above is the line through the center of the central mass perpendicular to the plane of motion.
