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. [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
The asteroid and comet belts orbit the Sun from the inner rocky planets into outer parts of the Solar System, interstellar space. [16] [17] [18] An astronomical unit, or AU, is the distance from Earth to the Sun, which is approximately 150 billion meters (93 million miles). [19]
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. An asteroid that’s somewhere between 30 and 100 feet ...
An Earth-crosser is a near-Earth asteroid whose orbit crosses that of Earth as observed from the ecliptic pole of Earth's orbit. [1] The known numbered Earth-crossers are listed here. Those Earth-crossers whose semi-major axes are smaller than Earth's are Aten asteroids; the remaining ones are Apollo asteroids. (See also the Amor asteroids.)
2012 LZ 1 is an asteroid classified as near-Earth object and potentially hazardous asteroid of the Amor group, approximately 1 km (0.62 mi) in diameter. [4] It passed within 5.4 million kilometers (14 lunar distances ) of Earth on 14 June 2012. [ 4 ]
2012 EG5 is an Apollo near-Earth asteroid with an estimated diameter of 47 meters (154 ft). [3] The asteroid was discovered on March 13, 2012. The asteroid came within 0.001539 AU (230,200 km ; 143,100 mi ) of Earth during its closest approach on April 1, 2012, [ 2 ] just over half the distance between Earth and the Moon's orbit.
An asteroid that crashed into the Earth’s atmosphere over the UK and France was spotted just hours before it crashed. The world was given only seven hours warning that it was being approached by ...
