WebAccording to Kepler’s laws, Mercury must have the shortest orbital period (88 Earth-days); thus, it has the highest orbital speed, averaging 48 kilometers per second. At the opposite extreme, Neptune has a period of 165 years and an average orbital speed of just 5 kilometers per second. All the planets have orbits of rather low eccentricity. WebDec 20, 2024 · Orbital Velocity(km/s or miles/s) - The average velocity or speed of the planet as it orbits the Sun, in kilometers per second or miles per second. * For the Moon, the average velocity around the Earth is given.
