A list of known near-Earth asteroid close approaches less than 1 lunar distance (384,400 km or 0.00257 AU) from Earth in 2009. [note 1] Rows highlighted red indicate objects which were not discovered until after closest approach
2009 DD 45 is a very small Apollo asteroid that passed near Earth at an altitude of 63,500 km (39,500 mi) on 2 March 2009 at 13:44 UTC.It was discovered by Australian astronomers with the Siding Spring Survey at the Siding Spring Observatory on 27 February 2009, only three days before its closest approach to the Earth.
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.
In January 2011, near-Earth asteroid 2009 FD (with observations through 7 December 2010) was listed on the JPL Sentry Risk Table with a 1 in 435 chance of impacting Earth on 29 March 2185. [20] In 2014 (with observations through 5 February 2014, creating an observation arc of 1807 days) the potential 2185 impact was ruled out. [ 22 ]
A menacing asteroid named Apophis is projected to have a close encounter with Earth in 2029, but scientists have long ruled it out as an impact risk. Asteroids safely fly by Earth all the time ...
