what is considered a High Kerban Orbit (HKO)?

What orbit is considered to be a HKO?

[MalfunctionM1Ke]

Half way to the Mun? Maybe everything beyond a stationary Orbit?

I actually dont know

Do you mean for science? It's 250 km (http://wiki.kerbalspaceprogram.com/wiki/Science#Celestial_body_multipliers).

If you mean for jargon, it's whatever you want it to be.

According to the science of reality, it's anything above geosynchronous: http://en.wikipedia.org/wiki/High_Earth_orbit

So, in the case of Kerbin, anything about 2868.75km, roughly 1/4 of the way to the Mun.

For all intents and purposes it doesn't really matter. LKO is just that thing people put rockets at when they launch them without any need to go higher, and HKO is "greater than LKO".

The "high/low" for Science! is listed at the bottom of this page for all bodies: http://wiki.kerbalspaceprogram.com/wiki/Science

I typically would say LKO is any orbit with a periapsis of >23 km and an apoapsis <250 km.

MKO is a more-or-less circular orbit between 250 km and 2868.75 km.

HKO is above KEO.

Just my idea of it.

LKO basically is just an orbit that you have if you just want to be in space. Generally 80-100 km is probably the best option, this allows for something to orbit below you and reach you quickly.
