Initially thrusting opposite to my direction of motion gets me closer to the gravity source.

At the closest point thrusting in my direction of motion lets me shoot outwards away from it carrying my momentum.

At the farthest point thrusting opposite my direction and away from the gravity source allows me to hold my position.

Then thrust in the direction to "catch up" with the moving rendezvous circle.

Then I had to thrust in the opposite direction of motion to stay within the circle so I wouldn't overshoot it.
