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.
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] Rows highlighted red indicate objects which were not discovered until after closest approach
The average near-Earth asteroid, such as 2019 VF 5, passes Earth at 18 km/s. The average short-period comet passes Earth at 30 km/s, and the average long-period comet passes Earth at 53 km/s. [8] A retrograde parabolic Oort cloud comet (e=1, i=180°) could pass Earth at 72 km/s when 1 AU from the Sun.
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 ...
An asteroid-like object with an apparent magnitude of 19.4 was spotted with cometary activity from images taken by the Lincoln Near-Earth Asteroid Research survey on the night of 8 December 2012. [1] From April 2014 onwards, the comet slowly faded away as it made its way back to the outer Solar System.
The Sutter's Mill meteorite is a carbonaceous chondrite which entered the Earth's atmosphere and broke up at about 07:51 Pacific Time on April 22, 2012, with fragments landing in the United States. [ 6 ] [ 7 ] The name comes from Sutter's Mill , a California Gold Rush site, near which some pieces were recovered.
A small asteroid will be pulled into orbit around the Earth as a “mini-moon” later this month before the space rock departs into other parts of the solar system.. The 10m-wide asteroid, dubbed ...
The Novato meteorite is an ordinary chondrite which entered the Earth's atmosphere and broke up over Northern California at 19:44 Pacific Time on 17 October 2012. The falling bolide created a bright fireball and sonic booms and fragmented into smaller pieces as the intense friction of passing through the atmosphere heated it and absorbed its kinetic energy. [2]
