The small near-Earth asteroids 2008 TC 3, 2014 AA, 2018 LA, 2019 MO, 2022 EB 5, 2022 WJ 1, 2023 CX 1, 2024 BX 1, and 2024 RW 1 are the only nine asteroids discovered before impacting into Earth (see asteroid impact prediction). Scientists estimate that several dozen asteroids in the 6–12 m (20–39 ft) size range fly by Earth at a distance ...
This is a list of asteroids that have impacted Earth after discovery and orbit calculation that predicted the impact in advance. As of January 2024 [update], 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. Asteroid designation.
99942 Apophis (provisional designation 2004 MN4) is a near-Earth asteroid and a potentially hazardous object with a diameter of 370 metres (1,210 feet) [ 3 ] that caused a brief period of concern in December 2004 when initial observations indicated a probability up to 2.7% that it would hit Earth on April 13, 2029.
Free-air gravity anomaly over the Chicxulub structure (coastline and state boundaries shown as black lines) The Chicxulub crater (IPA: [t͡ʃikʃuˈluɓ] ⓘ cheek-shoo-LOOB) is an impact crater buried underneath the Yucatán Peninsula in Mexico. Its center is offshore, but the crater is named after the onshore community of Chicxulub Pueblo ...
The Chelyabinsk meteor is thought to be the biggest natural space object to enter Earth's atmosphere since the 1908 Tunguska event, [23] [24] [25] and the only one confirmed to have resulted in many injuries, [26] [Note 1] although a small number of panic-related injuries occurred during the Great Madrid Meteor Event of 10 February 1896.

near Papua New Guinea. Coordinates. 1°18′S 147°36′E / 1.3°S 147.6°E / -1.3; 147.6 [1] CNEOS 2014-01-08, also known as Interstellar meteor 1 (IM1), [2][3][4] was a 0.45 m (1.5 ft) meteor that impacted Earth on 8 January 2014 near the northeast coast of Papua New Guinea. It was claimed to be an interstellar object in a 2019 ...
Although the asteroid is close enough to Earth to be deemed a "potentially hazardous object," Farnocchia said there is no chance the asteroid will hit Earth. The asteroid would need to be within a ...
2019 OK[ a ] is a near-Earth asteroid noted for its sudden, surprise discovery on the day before it flew by at approximately 70,000 km (43,000 mi) in 2019. [ 4 ] The object's size is estimated at 57 to 130 metres (187 to 426 ft) across, the closest asteroid of such size discovered in 2019. [ 5 ] It is uncommon for asteroids of this moderately ...
