Space Station in low orbit around Kerbol

[LittleItaly]

How low is too low? I don't have any plugins like Deadly Reentry, so how close to Kerbol could I make a stable, non decaying orbit around the Sun? Any helpful tips when dealing with strictly Solar Orbit?

Thank you!

Kerbol does not have an atmosphere, and temperature is not properly simulated, so you can achieve ridiculously low orbits--I believe 1500 meters or so is the limit, before you enter a zone that causes automatic explosions. Basically, so long as you're not at risk of entering Moho's sphere of influence, you can have whatever orbit you like.
