Burn nodes help

@ColonelStriker i use burn nodes, when i use Green nodes to aim mars the circle is bigger and before the circle reach mars it become smaller and go the other side where i aim, i really noob

You aim Mainly using green and blue nodes. Green to get to there, blue to reassure “angle” of approach. Red is when the planet is not in the same angle (viewed sideways) to you.

In the most basic possible terms:
Blue: “angle” of orbit if viewed top down
Green: how elongated said orbit is
Red: angle of orbit if viewed from the side
