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, based on the close approach database of the Center for Near-Earth Object Studies (CNEOS).
November 8 is the 312th day of the year ... 2011 – The potentially hazardous asteroid 2005 YU55 passes 0.85 lunar distances from Earth ... (d. 2021) [19] 1929 ...
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]
There is no threat of a collision with our planet now or for centuries to come, Nasa said.
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”.
The asteroid, named 2021 NY1, is classified as a Near-Earth Object and is roughly 580 feet long, making it more than two times taller than Lady Liberty standing in New York Harbor and more than ...
Goldstone radar images of asteroid 99942 Apophis on 8–10 March 2021 Goldstone radar images of asteroid 2001 FO 32 during closest approach on 21 March 2021 Below is an example list of near-Earth asteroids that passed or will pass more than 1 lunar distance (384,400 km or 0.00256 AU) from Earth in 2021.
NASA observes the asteroid YU 55 as it makes a close Earth flyby, passing within 0.85 lunar distances (about 201,700 miles) of the Earth. YU 55 is approximately 400 metres (1,300 ft) across, and is the largest asteroid to make a close pass since 1976.
