    Now go to the SOHO Movie Theater https://soho.nascom.nasa.gov/data/Theater/ and choose the C3 image at 512 image resolution, the dates Aug 30 to Sept 1 and generate the images, and watch the neat celestial (solar system) orbital mechanics of Venus, Mars and Mercury.  Notable is the faster orbital motion of Mercury (than Venus) as it swings into superior conjunction and the slower motion of dim Mars (with respect to the background star Regulus on the far right) as Earth overtakes it and Mars moves towards conjunction with the sun.  (No need to download the 250+ images generated; just use the buttons below the first image to play the sequence)!
