Energy for all orbits with the same SMA aren't identical

I'm not sure if I made a logical error here, but the claim, that for all orbits with the same SMA around the same body the energy is identical is incorrect:

All orbits with the same semi-major axis have the same energy.

This article from the beginning

When you reorder the formula there is something like this where and are the kinetic and potential energy divided by the mass. So and as (the specific orbital energy) is identical for all orbits with the same SMA (see specific orbital energy on Wikipedia), additionally depends on the mass of the craft.

I would suggest to write the section in a manner that covers also the SOE. It is easier to calculate because you don't require the mass of the craft and it has still the same implication: Is the sum greater than zero it is a hyperbolic orbit. — xZise [talk] 13:42, 22 September 2013 (CDT)
