WebFeb 6, 2024 · Kepler's Third law can be used to determine the orbital radius of the planet if the mass of the orbiting star is known ( R 3 = T 2 − M s t a r / M s u n, the radius is in AU and the period is in earth years). The Fastest Path from one Planet to Another Kepler's 3rd law can also be used to determine the fast path (orbit) from one planet to another. WebSince energy and momentum is conserved, energy and angular momentum in an orbit remains constant unless a burn is applied. Thus, it is possible to equate the specific mechanical energy of a general conic (Eqn. 19) with the sum of the kinetic and potential energy of an orbit (Eqn. 8) to obtain the velocity at any point in the orbit (see algebraic …
