The closer an object is to the Sun the faster it needs to move to maintain the orbit. Objects move fastest at perihelion (closest approach to the Sun) and slowest at aphelion (furthest distance from the Sun). Since planets in the Solar System are in nearly circular orbits their individual orbital velocities do not vary much. Being closest to the Sun and having the most eccentric orbit, Mercury's orbital speed varies from about 59 km/s at perihelion to 39 km/s at aphelion. maleth fleetWebTo isolate the velocity, take the cross product of this equation with the angular momentum, (5.2) By means of the bac-cab rule ( Equation 2.33 ), the left side becomes But h · h = h2, and v · h = 0, since v is perpendicular to h.
