2009 FD imaged by the Very Large Telescope in November 2013. 2009 FD was initially announced as discovered on 16 March 2009 by La Sagra Sky Survey. [14] Because there were previous observations found in images taken by the Spacewatch survey some 3 weeks prior, on 24 February 2009, the Minor Planet Center assigned the discovery credit to Spacewatch under the discovery assignment rules.
343158 Marsyas (prov. designated 2009 HC 82) is an asteroid on a retrograde orbit, classified as a large near-Earth object of the Apollo group. It may be an extinct comet or damocloid asteroid. The asteroid was discovered on 29 April 2009, by astronomers with the Catalina Sky Survey at the Catalina Station near Tucson, Arizona, in the United ...
[1] 2009 RR was the only asteroid discovered before 2014 that was predicted to potentially pass inside the orbit of the Moon during 2014. The asteroid has an estimated diameter of 26 meters (85 ft) and is listed on the Sentry Risk Table. [3] It is not large enough to qualify as a potentially hazardous object.
Because 2009 BD is a very small multi-opposition near-Earth object, the effect of radiation pressure on the orbit caused by light from the Sun was able to be detected. [4] The radiation-related acceleration allowed the Area to Mass Ratio (AMR) to be estimated at (2.97 ± 0.33) × 10 −4 m 2 /kg.
NASA's DART mission was a success. Images taken by satellite show plumes from the asteroid impact, but it could take weeks to monitor for changes in the asteroid’s trajectory.

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.
