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]
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.
The asteroid had a close approach to the Earth on 29 May 2012, approaching to only ~8950 miles (~14,440 km) above the planet's surface. 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.
Crooked Creek is an impact crater in Crawford County, Missouri, United States. It is 4.3 miles (7 km) in diameter and the age is estimated to be 320 ± 80 million years ( Mississippian ). The crater is exposed to the surface.
A similar scenario unfolded in 2004 with Apophis, an asteroid initially projected to have a 2.7% chance of striking Earth in 2029. Further observations ruled out an impact. "City killer" category
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 ...
An asteroid that’s somewhere between 30 and 100 feet long is hurtling through space in the direction of Earth at 30,000 miles per hour. Asteroid 2012 TC4 is going to fly by Earth on October 12 ...
The table below is arranged by the continent's percentage of the Earth's land area, and where Asian and Russian structures are grouped together per EID convention. The global distribution of known impact structures apparently shows a surprising asymmetry, [ 37 ] with the small but well-funded European continent having a large percentage of ...
