For example, at the L1 point, which lies between Earth and the sun, the sun'sgravitywill pull a spacecraft around it faster than Earth orbits the sun. (Kepler's second law of planetary motion tells us that the closer an object is to the sun, the faster it will orbit.) However, Ear...
Kepler's third law of planetary motion states that the square of each planet's orbital period is proportional to the cube of...
