Also known as
Planet X. The supposed tenth planet to our solar system. Nibiru has an unusual
orbit, it only comes near to the sun once every 3,600 years, meaning you'll probably never see it in your life time, although some say it will be returning very soon. Though no
astronomical evidence exists to support the planet's existence, some say that evidence lies in ancient
Sumerian inscriptions.
The inscriptions show the regular nine planets plus the Earth's moon plus an additional planet. Some cite these as astronomical charts which others say that they were purely decorational. According to some, the planet Nibiru will be coming back round very soon.
So keep watching the skies...
