A question probably simple for someone else...

... but that would require me to do a lot of potentially-miscalculation fraught work on my own:

Is it possible to have a geostationary (or europastationary?) orbit around Europa, and if so, at what altitude from the surface of the moon woudl that be?

IMHO it would have to be at the "Trojan" points (L4, L5 la grange points) since Europa's rotation is tidally locked to Jupiter and those wouldn't be very close to Europa... i am guessing around 100,000 km or more away.

I should think that the L1 or L2 points would better meet the concept of a "Europasynchronous" orbit than a Trojan position. I'm not sure how stable the points would be, what with Jupiter's magnetic fields, or if the L1 and L2 points are sufficiently distant from Europa's core to not be influenced by atmosphere.
