Some years back old Pluto was demoted from planet status to something smaller. I never agreed with that but am not part of the astronomical matrix of bigger brains. Now, it is possible we have another one orbiting our sun. It is out past Neptune. The new ninth planet. Its perigee is about 15 to 20 AU (Astronomical Units or the distance from the Earth to the Sun). So it is a fer piece away. What does this mean? Well, in 1976, a writer postulated that ancient Sumer was advanced by aliens from a ninth planet, Nibiru. Supposedly, Nibiru gets within travel distance with the Earth about every 3,600 years. His theory is based upon interpretation of Sumerian art and artifacts. I am not claiming validity here. It is just interesting that there may be such a planet with a long period orbit around our sun.
