If a planet orbiting around the sun, then what is the Velocity of a Planet at Apogee and Perigee ???
 

For the below figure

r_1=r_{p}=a-c

r_2=r_{a}=a+c

If Eccentricity is given by

 (e) = \frac{c}{a}

Then the velocity of the planet at Apogee and Perigee in terms of Eccentricity is given by

V_{a}=\sqrt{\frac{GM}{a}\left ( \frac{1-e}{1+e} \right )}

 

V_{p}=\sqrt{\frac{GM}{a}\left ( \frac{1+e}{1-e} \right )}

Where

V_{p}= Velocity \ of \ perigee

V_{A}= The velocity of the planet at apogee
