No. At least, not for the next few million years.
Yes scientist think that years ago ,before dinosouars were on earth,the planet hit the edge of earth and then started going around the earth as it got smaller
NO! And the proof is its already 2013 no hit and earth isnt in the middle of the solar system and many planets are in it so I say planet x isnt going to collide with earth and if it is a meteorite then theres a really big chance planet x hits the huge sun and melts there
The world is not coming to an end, and the planet nibiru is not going to hit the Earth. The world does have lots of real problems, which I would generally categorize as political, economic, and environmental, and these problems may get much worse, but the world will nonetheless not come to an end. What is this 'Planet Nibiru'? Not one of the usual ones in our solar system.
We don't currently know when a comet will hit planet Earth.
They will hit Earth if, in their orbit around the Sun, they happen to cross Earth's orbit.
No, there is no evidence to suggest that Nibiru, a hypothetical planet, is going to tilt the Earth. Nibiru is considered to be a conspiracy theory and there is no scientific basis for its existence or impact on Earth's tilt. Earth's tilt is primarily determined by its natural processes and interactions with other celestial bodies in the solar system.
Imposible
Of course not! There is no such thing as Planet-X!
Going outwards from the Sun, the next planet in the solar system after Earth would be Mars. Going inwards from Earth towards the Sun, the next planet is Venus - whose orbit is actually closer to Earth's than that of Mars.
The name of the (proto)planet that hit (proto)Earth in the Giant Impactor hypothesis is Theia.
There is no special name for them. Any planet can hit by them. Earth gets hit by them.
the biggest asteroid to every hit earth was the one who wiped out nearly all the dinosaurs . but scientist's say on 21st of DEC 2012 a planet half the size of the earth was going to hit and cause fire tsunamis and complete destruction we don't know but we will know one day
