M=meters & K=kilometers???
The names I got from a sci-fi movie and show, Titan A.E. for the Keck and Farscape for the Metra.
Overall this system works better since two planets can't be 56.5 kilometers apart because their overlapping gravitational fields would either merge the two into one or obliterate both of them in a big mess of shifting magma and rocks and likely create an asteroid field, of which there are plenty in FL.
So am I off base or not here?...
