A rebuttal in Astronomy & Geophysics countered that Loeb et al. had ignored that the amount of iridium deposited around the globe, 2.0 × 10 8 –2.8 × 10 8 kg (4.4 × 10 8 –6.2 × 10 8 lb), was too large for a comet of the size implied by the crater, and that they had overestimated likely comet impact rates.
99942 Apophis (provisional designation 2004 MN 4) is a near-Earth asteroid and a potentially hazardous object, 450 metres (1,480 ft) by 170 metres (560 ft) in size, [3] that caused a brief period of concern in December 2004 when initial observations indicated a probability of 2.7% that it would hit Earth on Friday, 13 April 2029.
A human is more likely to die in a fire, flood, or other natural disaster than to die because of an asteroid or comet impact. [2] Another study in 1994 found a 1-in-10,000 chance that the Earth will be hit by a large asteroid or comet with a diameter of about 2 km (1.2 mi) during the
A six-mile-long asteroid, which struck Earth 66 million years ago, wiped out the dinosaurs and more than half of all life on Earth.The impact left a 124-mile-wide crater underneath the Gulf of ...
Although no human is known to have been killed directly by an impact [disputed – discuss], over 1000 people were injured by the Chelyabinsk meteor airburst event over Russia in 2013. [23] In 2005 it was estimated that the chance of a single person born today dying due to an impact is around 1 in 200,000. [24]
While the dinosaurs met their end around 66 million years ago in a catastrophic way, their extinction may have been crucial to the development of the human race.

The meteorite, S2, was first discovered in 2014. It hit the planet about 3.26 billion years ago and is estimated to have been up to 200 times larger than the space rock that later killed the ...
