I don't think this is necessary. I never wrote a conditional complicated enough to make me even think about getting down to K maps and I believe such a thing would be actually a smell and better be refactored as a whole. Knowing some boolean algebra is nice, though
The green line is actually the ecliptic, the path which the Sun travels on the celestial sphere. You may find all the other planets along it also, because it is coplanar with Earth's orbit around the sun and, as consequence, almost coplanar with the other planet's orbits.
