For a circular orbit, the semi-major axis ( a) is the same as the radius for the orbit. In fact, Equation 13.8 gives us Kepler’s third law if we simply replace r with a and square both sides.

WebJan 3, 2011 · Today, January 3, 2011, around 19:00 GMT (2:00 p.m. Eastern US time), the Earth reaches perihelion. At that time, we'll be about 147,099,587 kilometers (91,245,873 miles) from the Sun. To give you an idea of how far that is, a jet traveling at a cruising speed of 800 km/hr would take over 20 years to reach the Sun. WebThe perihelion and aphelion locations for earth can be as shown in the diagram. According to the Kepler's second law, areal velocity is constant. So, γp×vp =γA ×vA. γA γp = vp vA. Therefore, γA >γp. So, vp > vA. Therefore, the speed of the earth is more at the perihelion than at the aphelion. According to Kepler’s second law of ... WebMar 19, 2024 · The areal velocity of earth around the sun will always be constant. Hence, the speed of earth at aphelion is less than the speed of earth at perihelion.
