Kerbol is quite scannable, provided you bring enough ÃŽâ€v for your circularization burn(s). I think it should even be possible to scan it with BTDT, since the heat-exclusion zone (according to the wiki) is below the 2km BTDT scanning range. I've only scanned about 8%, because I didn't bring enough ÃŽâ€v, but I'm going to try again soon. I haven't had any issues with the stock science parts, using SCANSat, MechJeb, and RealChute, so my suspicions would center on MM, Kerbal Joint Reinforcement, and/or Romfarer.
