Retrograde motion

What it changes

What it governs gets replayed rather than launched. A good time to revisit, a bad one to sign without re-reading.

What it is

Seen from Earth, the planet appears to move backwards. It has not changed direction: we are overtaking it on our orbit, like passing a train.

The direct station

The planet resumes its normal apparent motion.

What has been dragging since the previous station becomes doable again.

See the calculated example
Diagram, orbits to scale: Earth (in blue) overtakes Mars. Seen from Earth, Mars moves backwards against the stars while it is being overtaken (in violet), then moves on.
