If an asteroid impact were to stop the Earth from rotating how big would that asteroid need to be?
MattElliott
size doesn't matter its the angle and speed of the asteroid that it is at, plus if that did happen the earth would either drift off into space and eventually get back into a orbit because of the suns gravity or explodes and everything would just flip, roll over, fall how ever you wanna put it. plus its nearly impossible for a asteroid to do that it would probably do what i said in the second sentence.

What is the percentage of an asteroid hitting earth in the next 100 years?
An asteroid or meteor that would cause climatic change, about 1 in 600,000 to 1 in 10,000,000.
How could a rock from Mars get to Earth?
Scientists think that asteroid impacts could send material from the Martian surface into space . Eventually those bits of rock could land on Earth as meteorites.The "escape velocity" for Mars is about 45% that of Earth, so it would still have to be a big impact, and obviously smaller stuff gets burned up in the atmosphere.Also the trajectory of the rocks would have to be right to get the rocks to Earth. That's why there have been so few meteorites from Mars found on Earth. On Earth, we're better protected from huge impacts by our own atmosphere, but it's a popular theory that the Moon was formed from ejected material from an impact, and you can be sure that the impact that killed the dinosaurs put material in space, so it's not impossible by any means.
If earth collided with asteroid where would you hide?
If the Earth collides with a large asteroid, the only place to hide would be "someplace else". Like, on the Moon or Mars. The Earth is small and fragile, and as long as 100% of the human race is living on the surface of the Earth, we have "all of our eggs in one basket". This is one of the primary reasons for going into space; to give us somewhere so that all of humanity won't be abruptly extinguished on one cosmic catastrophe.
How would a three hour time exposure photograph of Star in the norther sky appear if the earth didn't rotate?
If the Earth didn't rotate, then the camera would stay where you pointed it, and a three hour exposure would look just like a 1/60 second exposure except that everything would be a lot brighter.The fact that the Earth does rotate is a problem in astrophotography. To get long exposures, it's necessary to mount the telescope on a motorized base turning in the opposite direction to counteract the rotation of the Earth and keep the camera pointed at the same star for the entire length of the exposure ... if you don't, you get "trails" as the stars move across the camera's field of view. (Though really it's the camera that's doing most of the moving ... the stars are moving, but they're so far away that it takes a lot more than three hours for them to move noticeably.)
Is it possible to destroy an asteroid?
The only thing that destroys asteroids (until now) has been collisions with other objects; other asteroids, the Moon, the Earth, other planets or the Sun. (There have been asteroids that have fallen into the Sun!) When an asteroid collides with another asteroid, it doesn't actually destroy either asteroid; it just breaks both of them into smaller pieces.
How would earth change is an asteroid or comet would impact earth?

How will the world be when the asteroid falls on earth?
Which asteroid? depending on its size, an asteroid impact could be devastating for life on Earth, though life would recover somehow eventually.
What would happen if an impact caused earth to stop rotating?
If an impact caused the earth to stop rotating it would have already caused damage. For example: If a meteor hit the earth it would crack the earth into pieces, therefore we would be frozen in the darkness for half a year and toasted from the sun the other half.
How does the theory of asteroid impact relate to the extinction of Dinosaurs?
I does not. The asteroid would of had to knock out the entire earth for that to happen. If you think of the facts it is just not possible.
What could happen if an asteroid hit the earth?
if its bigger than isle of man it would do a very big impact and damage
If an asteroid or comet were on a collision course for earth what factors would determine how dangerous the collision might be for your community?
The size, speed, location and angle of impact of the object with the Earth. A major factor would be if the impact is on water or land.
The earth been destroyed by a asteroid?
No, if the Earth was destroyed by an asteroid we would not be living today.
How might an asteroid impact change Earth's climate?
When the asteroid strikes Earth, it would throw up a great deal of debris into the atmosphere. The debris would block much of the sun's light, thus causing global temperatures to fall and decreasing the amount of plant life that could survive on Earth.
If you were 80 pounds on earth how much would you weigh on an asteroid?
Depends on the mass of the asteroid
If a black hole or an asteroid hit earth what will happend to the ocean?
A black hole would eventually swallow up the entire Earth. An asteroid would provoke great catastrophes - depending, of course, on the mass of the asteroid.
Could a 70 mile wide asteroid destroy earth?
When talking about asteroidal impacts, it's worth noting that the diameter of an object is not an indication of potential impact. The density and more important is the velocity at which it impacts the Earth is. However, an asteroid with a diameter of 70 miles would not destroy the Earth. The Earth has been hit by much larger objects (Theia) and survived - yet only just. A 70 mile asteroid would make a large impact but it would not destroy the Earth. A 70 mile asteroid would however, with the right velocity and angle, in all probability, wipe all life off of the Earth and cause years of non regeneration. Simple life would eventually recolonise the planet, but it would take millions of years for complex animals to evolve. So much so, that a devastation on that scale would eliminate mankind from the Universe as we know it. The asteroid that wiped out the Dinosaurs and ended their reign was a mere 10 miles in diameter and produced 2 million times more energy that our most powerful atomic bomb. So the 70 mile asteroid would not destroy the Earth but it would certainly destroy everything on it.
What if the earth is not rotating on its axis?
Then the world would have no days or nights. We would just be either day or night depending on when the earth stopped rotating on it axis.
