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 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. [10] 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 ...
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.
