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 Rows highlighted yellow indicate objects discovered less than 24 hours before closest approach
Trajectory of 2004 FH in the Earth–Moon system Goldstone radar images of asteroid 2007 PA 8 's Earth flyby in 2012. This is a list of examples where an asteroid or meteoroid travels close to the Earth. Some are regarded as potentially hazardous objects if they are estimated to be large enough to cause regional devastation.
The 27 June 2011 close approach to Earth increased the orbital period of 2011 MD from 380 days to 396 days. During close approach the asteroid passed Earth at a relative speed of 6.7 km/s [1] with a geocentric eccentricity of 1.1. 2011 MD was observed by the Spitzer Space Telescope in February 2014 and estimated to be 6 meters (20 ft) in ...

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.
Set to pass between the star and Earth is Leona, a slightly oval-shaped asteroid located between the orbits of Mars and Jupiter. Leona is estimated to be about 50 miles (80 kilometers) by 34 miles ...
Each year, Earth passes through the debris trails, and pieces of dust and rock create colorful, fiery displays called meteor showers as they disintegrate in our planet’s atmosphere.
During the 1976 close approach the asteroid reached about apparent magnitude 14. [6] The asteroid will pass 0.00516 AU (772,000 km; 480,000 mi) from Earth on 27 December 2022, [4] [5] allowing a refinement to the known trajectory. The uncertainty region in 2013 suggested that the asteroid could have passed inside the orbit of the Moon in 1907 ...
