je propose la planete violette pour Sedna

History records many names for Planet X. The Sumerians called it the 12th planet or Nibiru (translates into; planet of passing). The Babylonians and Mesopotamians called it Marduk, The King of The Heavens and The Great Heavenly Body. The ancient Hebrews referred to it as the Winged Globe because of it's long orbit high among the stars. The Greeks called it Nemesis. (its most telling name) Prophets have named it The Blue Star, The Red Star, The Fiery Messenger, and The Comet of Doom among others. No matter what the name used, it's the same object that has the same effects before and during it's passage of earth. The Sumerians also had a name for it's approximate 3600 year orbit (A Shar). The ancient Hindu astronomers named Treta Yuga (3600 years) and the destruction it causes Kali Yuga.

Look to Discovering Archeology, July/August 1999, on page 72. The date 1628 B.C. is given for a world wide catastrophic event. Approximately 3600 years ago and coinciding with its return at this time. Page 70 shows a medieval picture with a large comet looking object as big as the sun streaking across the sky horizontally with a giant tail. Below is a town that is shaking apart with hysterical people in the streets.

Its elliptical orbit takes it around two suns. The other sun it orbits is our suns dark twin. Nibiru's inbound approach is being closely monitored by our best telescopic equipment on and off earth. This is one of many reasons the orbiting Hubble telescope live feed is hidden from our view. The most accurate calculation for Planet X's next passage is now late May or June 2003.
