Using M places a block in space in front of you. That block costs 1 million. If by accident it were to be misaligned and you removed it, there is no refund.
With this in mind, I reveal to you the horrible truth:
Using M doesn\'t align with the grid of whatever you\'d try putting it on. Much like a ship, the \"station block\" (just a piece of hull) needs room to be created and so, cannot be cretaed touching anything. That means you\'d have a station hovering above the planet at best.
So far, the only way to make a station out of an asteroid or a planet and having it considered an actual station object... is to build the asteroid/planet artificially around it..

I haven\'t tried any of that, but is it possible that claiming a planet (I know you can do that) allows you to set it as faction home? If so, would that protect the same way a sation would? I don\'t think so, since docking pads don\'t seem to work on something other than ships and stations...
A compromise solution would have your \"home base\" which docks and protects your ship be effectively in orbit above the planet. (I don\'t know if stations are affected by gravity.. hmm). That\'d pretty much make the actual land station a decoration but.. eh.
