The October 2012 observations reduced the orbit uncertainties by more than a factor of 60, meaning that the Earth's position in February 2040 no longer falls within the range of possible future paths for the asteroid. [8] On 4 February 2040 the asteroid will pass no closer than 0.007 AU (1,000,000 km; 650,000 mi) (~2.8 LD) from Earth. [1]
Trajectory of asteroid 2005 YU 55 compared with the orbits of Earth and the Moon on 8–9 November 2011. Apparent trajectory on 8–9 November 2011. In February 2010, (308635) 2005 YU 55 was rated 1 on the Torino Scale for a potential pass near Earth on 10 November 2103, [12] that posed no unusual level of danger.
A list of known near-Earth asteroid close approaches less than 1 lunar distance (384,400 km or 0.00257 AU) from Earth in 2011. [note 1] Rows highlighted red indicate objects which were not discovered until after closest approach
(436724) 2011 UW 158, provisionally known as 2011 UW 158, is a stony, walnut-shaped asteroid and fast rotator, classified as near-Earth object and potentially hazardous asteroid of the Apollo group, approximately 300 meters in diameter.
An asteroid the size of a football stadium will thread the needle between Earth and the moon Saturday morning — the second of two astronomical near misses in three days. Near miss, in this case ...
A "harmless" asteroid burned up Tuesday night above northern Siberia in Russia, creating a blazing fireball in the sky witnessed across the region.
A video titled "Asteroid Discovery From 1980 - 2010" was one of Manley's early YouTube successes. The video is a computer animation showing a time-lapse of the Solar System from 1980-2010. When the time-lapse reaches the day an asteroid is discovered, it appears on the map as a bright green dot and continues orbiting the Sun.
For comparison, the average distance between the Earth and the moon is about 385,000km (239,000 miles). So far, about 25,000 large asteroids have been discovered as potential “city killers”.
