Earth's perihelion and aphelion
WebAccording to Kepler's 2nd Law, planets move more slowly at aphelion than they do at perihelion. As a result, Northern summer on Earth is 2 to 3 days longer than southern summer -- which gives the Sun even more time to bake the northern continents.

Perihelion always occurs near … WebNov 22, 2024 · At perihelion and aphelion the velocities are purely tangential, so conservation of angular momentum yields r p v p = r a v a , a ( 1 − e) v p = a ( 1 + e) v a . Conservation of energy (potential plus kinetic) then gives − G M r p + v p 2 2 = − G M r a + v a 2 2 , − G M a ( 1 − e) + v p 2 2 = − G M a ( 1 + e) + v a 2 2 . Eliminating v a gives
