Hey guys
Well I'm doing a group assignment based on orbital mechanics and my partner found a formula for eccentricity which is:
e = h2 / μEarth / (radius at perigee) - 1
Anyway when calculating h he said it was angular momentum:
h = (radius at perigee)*(velocity at perigee)
But it can't be because there's no mass component, so I'm worried we used the eccentricity formula wrong. Is the above formula for h correct? If so, what is it called?
Thanks!
