(410777) 2009 FD is a carbonaceous sub-kilometer asteroid and binary system, [6] [3] classified as near-Earth object and potentially hazardous asteroid of the Apollo group, discovered on 24 February 2009 by astronomers of the Spacewatch program at Kitt Peak National Observatory near Tucson, Arizona, in the United States. [2]
[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.

2009 RY 3 (~41 meters in diameter) passed 1.94 Lunar distances (745,000 km) from Earth on 11 September 2009. 2009 SH 1 (~5 meters in diameter) may have passed as close as 1.01 Lunar distances (390,000 km) from Earth on 14 September 2009, but the nominal orbit suggests an approach nearer to 2.40 LD (922,000 km).
It was the most powerful asteroid strike in more than 100 years, and left around 1,500 people injured as well as causing significant damage to buildings and blowing out windows. Show comments ...

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.
