A list of known near-Earth asteroid close approaches less than 1 lunar distance (384,400 km or 0.00257 AU) from Earth in 2012. [note 1] Rows highlighted red indicate objects which were not discovered until after closest approach Rows highlighted yellow indicate objects discovered less than 24 hours before closest approach
Trajectory of 2004 FH in the Earth–Moon system Goldstone radar images of asteroid 2007 PA 8 's Earth flyby in 2012. This is a list of examples where an asteroid or meteoroid travels close to the Earth. Some are regarded as potentially hazardous objects if they are estimated to be large enough to cause regional devastation.
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 .
A small asteroid was visible in northern Siberia on Tuesday, as it closed in on its collision course with Earth. The European Space Agency issued an alert for the 27-inch asteroid at 4:27 a.m. ET ...
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.
(614689) 2020 XL 5 (provisional designation 2020 XL 5) is a near-Earth asteroid and Earth trojan discovered by the Pan-STARRS 1 survey at Haleakala Observatory, Hawaii on 12 December 2020. It oscillates around the Sun – Earth L 4 Lagrangian point (leading 60°), one of the dynamically stable locations where the combined gravitational force ...
The asteroid making so much news today ranks as a three, representing “a chance of collision capable of localized destruction.” Read More : NASA’s New, $4 Billion Space Telescope Will ...
Three years later, in 2012, the 40 meter diameter asteroid 367943 Duende was discovered and successfully predicted to be on close but non-colliding approach to Earth again just 11 months later. This was a landmark prediction as the object was only 20 m × 40 m , and it was closely monitored as a result.
