[24] [16] Using NASA's estimated diameter, mass, and density for 2024 YR 4, the asteroid would release energy equivalent to 7.8 megatonnes of TNT (32.6 PJ) if it were to impact Earth at its predicted velocity at atmosphere entry of 17.32 km/s (10.76 mi/s), [7] equivalent to about 367 of the "Fat Man" bomb dropped on Nagasaki, 2 and a half of ...
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, April 13, 2029.

The asteroid will not come this close to Earth again until March 2027. [11] By May 2022, when the asteroid was 1 AU from the Sun and near the ecliptic, Earth was on the other side of the Sun, 1.9 AU from the asteroid. [12] The asteroid is not risk listed. 2022 AP 7 's orbit is well-determined and will guarantee only distant approaches beyond 1. ...

For comparison, the average distance between the Earth and the moon is about 385,000km (239,000 miles). So far, about 25,000 large asteroids have been discovered as potential “city killers”.
This is a list of asteroids that have impacted Earth after discovery and orbit calculation that predicted the impact in advance. As of December 2024, all of the asteroids with predicted impacts were under 5 m (16 ft) in size that were discovered just hours before impact, and burned up in the atmosphere as meteors.
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 ...
