This vedio shows the retrograde motion of Mercury in the geocentrism, i.e, from the Earth-hased perspective. Mercury is the closest planet to the Sun with an orbital period of 87.9691days (0.24085 yr).

The geocentrism was a historical model and superseded by heliocentric models. Acturally, many pheonomena observed on Earth can be explained by the geocentric model, e.g., the retrograde motion of Mercury.
