Directions to my house

Sometimes I wonder, if you met someone at a bar and grill (I added the grill part for non-drinkers like me) on another planet, what you would scribble on a napkin for directions to your house? Certainly it might include handing them something like the above.  They might say,

Well, which planet is it?

and you might say,

Wait, I have a picture in my wallet right here. You can have it.

then you ask the bartender for a red magic marker, non-erasable, and you put this arrow on the photo.

then the other person says,

Got it! Blue and green planet, next to the dead one. I should land in the field next to the U Tote Em.

Right. Watch out for the fire ants.
