  • Is there a planet Nibiru which is reported to come close to Earth on 12 December 2012?
  • No, there is no such planet Nibiru. Nibiru is also often called Planet X. According to hoaxists, Nibiru is a planet that was discovered by the Mayans that will collide with the Earth on December 21st, 2012. This is just one of the "theories" about the world ending in 2012. The truth is, the Mayans knew of no such planet. Although they were very skilled at tracking the motions of the planets, Sun and Moon, they did not know what the planets were. They would have only been able to see the 5 naked eye planets; Mercury, Venus, Mars, Jupiter and Saturn. Telescopes had not yet been discovered. If there is a planet called Nibiru it would have to be very large or very close to Earth in order for the Mayans to see it. And if it is very large or very close, then you and I would be able to see it today. If it were on a collision course with Earth, it would get brighter and brighter until we could even see it in the daylight. But of course, we can't, because it doesn't exist. Rest easy tonight, the world will continue well past the year 2012.

  • Is there a planet or brown dwarf called Nibiru or Planet X that is approaching the Earth and threatening our planet with widespread destruction?
  • Nibiru and other stories about wayward planets are an Internet hoax. If Nibiru or Planet X were real and headed for an encounter with the Earth in 2012, astronomers would have been tracking it for at least the past decade, and it would be visible by now to the naked eye. Obviously, they do not exist.

  • Isn't it possible that other planets rotate in and out of our solar system on longer cycles in elliptical orbits. E.G. Nibiru at 3,600 year cycles that our current civilization has not observed?
  • Although it is theoretically possible that more planets exist in our solar system that we have not detected, it is very unlikely. Everything in the universe has gravity, and this gravity effects everything in the universe. The closer 2 objects are to each other, the more their gravity effects surrounding objects. The same is true for large objects. The larger the object, the more gravity will effect surround objects. These effects are measurable by astronomers, even outside our own solar system. Astronomers have used this technique to find hundreds of planets in orbit around other stars. Since we have never seen any gravitational interaction on our Sun or the planets in our solar system, astronomers believe there are not any very large planets beyond the orbit of Pluto.

  • There is an apocalypse that the world is going to end in 2012 which has been supported by astrophysical theories. Is that so? Or do the scientists believe the world will end based on Biblical beliefs?
  • No scientist has predicted an apocalypse for 2012. This is an internet hoax that has been going on for years. It is based on the belief that the Mayans "predicted" the world ending on December 21st, 2012, the end of the calendar. But just as the world doesn't end on December 31st each year when our calendar ends, the world will not end when the Mayan calendar ends - it will simply start a new cycle. There are many more articles about the apocalpyse, 2012, Nibiru and other related topics on this page and many NASA sites. We encourage everyone to read up on it.

  • What is the origin of the prediction that the world will end in 2012?
  • The story started with claims that Nibiru, a supposed planet discovered by the Sumerians, is headed toward Earth. This catastrophe was initially predicted for May 2003, but when nothing happened the doomsday date was moved forward to December 2012. Then these two fables were linked to the end of one of the cycles in the ancient Mayan calendar at the winter solstice in 2012 -- hence the predicted doomsday date of December 21, 2012.
