2012 KT42 is an Apollo near-Earth asteroid first observed by astronomer Alex R. Gibbs of the Mount Lemmon Survey with a 1.5-meter reflecting telescope on 28 May 2012.
Overview [ edit ]
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 KT42 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 KT42 passed roughly 0.01 AU (1,500,000 km ; 930,000 mi ) from Venus on 8 July 2012.[1]
It is estimated that an impact would produce an upper atmosphere air burst equivalent to 11 kt TNT ,[4] roughly equal to Hiroshima's Little Boy . The asteroid would be vaporized as these small impacts occur approximately once per year. A comparable-sized object caused the Sutter's Mill meteorite in California on 2 April 2012. It was removed from the Sentry Risk Table on 30 May 2012.[5]
