Sahasrara(Jupiter) is paired with Muladhara(Saturn)
Pineal Gland(Moon) is paired with Manipura(Sun)
Vissudhi(Venus) is paired with Svadhisthana(Mars)
Anahata(Mercury) is the connector, the MEDIator.
And Uranus, Neptune, and Pluto all rule the chakras in the head.
I gather that each Chakra pair is to be united and not just the Moon and Sun Chakras.
