Day 19: Retrograde Motion of Mars


Astronomy: First we used Stellarium to keep track of Mars’s location in the zodiac each month for a whole year.

Then we used stoppers to model the motion of the Mars against the constellations as seen from Earth (animated GIF above).

Handouts: Planetary Motions Star Chart and Retrograde Mars Model.
