An asteroid capable of flattening a mid-sized city could potentially collide with Earth eight years from now, as its orbit around the sun briefly intersects the path of our planet. Named 2024 YR4 ...
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.
2024 YR 4 orbits the Sun on an elliptical orbit that crosses Earth's orbit, making it an Apollo-type near-Earth object. [3] The asteroid has an orbital period of about 3.99 years and an orbital inclination of 3.41 degrees with respect to Earth's orbit . [3] The asteroid came to perihelion (closest approach to the Sun) on 22 November 2024.

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”.
2024 RW 1, previously known under its provisional designation CAQTDL2, [5] was a 1-meter-sized asteroid or meteoroid that struck the Earth's atmosphere and burned up harmlessly on September 5, 2024, at around 12:40 a.m. PHT (September 4, 16:40 UTC) above the western Pacific Ocean near Cagayan, Philippines.
The asteroid, called 2024 UQ, was first spotted on 22 October by the Asteroid Terrestrial Impact Last Alert System, or ATLAS, a telescope network scanning the sky for space rocks likely headed for ...
2024 ON is a near-Earth object with a length around 350 meters [2] that flew past Earth on 17 September 2024 at a distance of 620,000 miles (1,000,000 km). [3] It was discovered by ATLAS-MLO, Mauna Kea on 27 July 2024. [2] Radar observations showed that 2024 ON is a contact binary.
