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, based on the close approach database of the Center for Near-Earth Object Studies (CNEOS). [1]
This is a list of asteroids that have impacted Earth after discovery and orbit calculation that predicted the impact in advance, which are cataloged by the Center for Near-Earth Object Studies (CNEOS). [1]
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.
An asteroid for which there is some possibility of a collision with Earth at a future date and which is above a certain size is classified as a potentially hazardous asteroid (PHA). Specifically, an asteroid is a PHA if its Earth minimum orbital intersection distance (MOID) is <0.05 AU and its absolute magnitude is 22 or brighter. [2]
The small asteroid, measuring about a metre across, did not pose a threat to life. It was the third space rock detected imminently before impacting the Earth this year, but only the tenth on record.
An asteroid streaked past northern Siberia in the middle of the night Tuesday before burning up in Earth’s atmosphere, lighting up the skies with a blinding flash, dramatic video shows.
This means 2012 KT 42 came inside the Clarke Belt of geosynchronous satellites. In May 2012, the estimated 5- to 10-metre-wide asteroid ranked #6 on the top 20 list of closest-approaches to Earth. There was no danger of a collision during the close approach. 2012 KT 42 passed roughly 0.01 AU (1,500,000 km; 930,000 mi) from Venus on 8 July 2012. [1]
