Challenge: Lowest Orbit

[Geometrian]

Challenge: On any body of your choice, set up the lowest orbit possible. The orbit must be stable for 300 seconds after the submitted image.

For example, my attempt on Minmus (taken a regrettable few seconds after perihelion, where it was about ²/₃ the height):

There's a Challenge Section for a reason, mate.

Look for a Limbo Challenge

So is it the lowest periapsis that counts?

does it matter if I start by accelerating a craft to 2/3rds the speed of light and then sending it through the lower atmosphere of Laythe?

[Pds314]

Okay. You are probably not gonna like it. But its not my fault that you let me do this. Periapsis of 1 meter, orbit makes no collision with Minmus until 17 hours later and there is plenty of fuel available to make course correction if needed.

I win. It is an orbit. It has a periapsis and an apoapsis.

1m, lol, glad I didn't have to clean that suit afterwards.

inb4 the OP decides it's judged by the semi-major axis.

But yeah, unless the intention is to allow suborbital trajectories and orbits that may eventually hit terrain, the requirement should be revised to one complete orbit.
