How big of an asteroid would it take to destroy the Earth?
about 96 km
Ultimately, scientists estimate that an asteroid would have to be about 96 km (60 miles) wide to completely and utterly wipe out life on our planet.
How likely is Earth to get hit by an asteroid?
Asteroids with a 1 km (0.62 mi) diameter strike Earth every 500,000 years on average. Large collisions – with 5 km (3 mi) objects – happen approximately once every twenty million years.
What would happen if the moon was hit by an asteroid?
The Moon is very big, and any small object hitting it would have very little effect on its motion around the Earth, because the Moon’s own momentum would overwhelm that of the impact. Most asteroid collisions would result in large craters and little else; even the largest asteroid known, Ceres, wouldn’t budge the Moon.
How far away is the asteroid from Earth?
That is somewhere between 329-478 million km away. The asteroid belt is huge and the space between each of the asteroids is over 600,000 miles. The circumference of Earth is only 24,901.45 miles, which means that the distance between objects in the asteroid belt is more than 24 times the circumference of Earth.
What is the closest asteroid to hit Earth?

Are there any asteroids close to Earth?
The 104 metre-wide space rock, which Nasa call Asteroid 2013 YD48, will come within 3.48 million miles of our planet as it whizzes through space. There are no asteroids in existence that currently pose a threat to Earth, but Nasa are getting ready just in case.
What is the closest meteor to Earth?
NASA is keeping an eye on asteroid 1994 PC 1 for many decades and it is a Near-Earth Object since it is closer than 1.3 astronomical units (AU), with one AU being equivalent to 93 million miles. However, the closest approach of asteroid 1994 PC 1 to Earth
