An animation to explain the (apparent) retrograde motion of Mars, using actual 2020 planet positions
Summary
[edit]| Description |
English: An astronomical explanation for Mercury's retrograde motion: the inner planet appears to retrace its steps a few times per year. Every planet does this, every year. In fact, there is a planet in retrograde for 75% of 2020. |
