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 ]
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 [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 .
The impact site was not examined by scientists until 20 years later, when they discovered the asteroid carved a massive area of destruction of around 830 square miles, according to NASA.
Recent images released from NASA have revealed new information on the origins of the asteroid system. Nearly two years ago, the Double Asteroid Redirection Test spacecraft, or DART, collided with ...
An asteroid burned up in the Earth’s atmosphere just hours after it was detected last month, the European Space Agency revealed in its latest newsletter.. The asteroid, called 2024 UQ, was first ...
2024 BX 1 is the eighth asteroid discovered before impacting Earth, and is Sárneczky's third discovery of an impacting asteroid. Before it impacted, 2024 BX 1 was a near-Earth asteroid on an Earth-crossing Apollo-type orbit. The bolide was studied in June 2024. It had a steep entry of 75.6° and an entry speed of 15.20 km/s.
The asteroid, described as "very small" by NASA, impacted Earth's atmosphere around 11:14 a.m. ET and created a fireball over eastern Russia, the space agency said in a post on X.
In September 2013, there was an opportunity to make additional observations of 2011 AG 5 when it came within 0.98 AU (147,000,000 km; 91,000,000 mi) of Earth. [10] The 2013 observations allowed a further refinement to the known trajectory. The asteroid will also pass 0.0121 AU (1,810,000 km; 1,120,000 mi) from the Earth on 3 February 2023.
