Great for retrograde periods and their shadows for all planets, especially Mercury, Venus, Mars. Retrogrades are when certain planets appear to be traveling backward in our viewing sky. Of course, a nod to Neptune and Jupiter. This planetary energy is wielded by the Ruler of the planet such as Uranus, Pluto, Saturn, etc. and their archetype/personality is what is reflected, so may appear a bit catawampus. We are the stationary planet along with the Sun and Moon.
