## 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. ”

When you reorder the formula there is something like this $E=\epsilon _{k}\cdot m+\epsilon _{p}\cdot m$ where $\epsilon _{k}$ and $\epsilon _{p}$ are the kinetic and potential energy divided by the mass. So $E=\epsilon \cdot m$ and as $\epsilon$ (the specific orbital energy) is identical for all orbits with the same SMA (see specific orbital energy on Wikipedia), $E$ 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)

## Adding Deep space kraken?

I am putting it in the see also for now, because it is a valid term in the ksp universe.

If anyone wants to do anything different, yell at me, or do it your self. :) — Preceding unsigned comment added by HamShanky (talkcontribs) 00:58, 20 September 2014‎ (UTC)
