Let be mass of planet and
that of sun,
the radius between the two. Let the planet be moving with velocity
then
Gravitational force = centripetal force
Hence, larger the distance, smaller the orbital velocity. At point distance from sun is maximum, hence orbital velocity is lowest. At point
distance from sun is minimum, hence orbital velocity is maximum.
