is a kilometer-length near-Earth asteroid and potentially hazardous asteroid of the Apollo group. It was discovered by LINEAR on 13 January 1999.
On 7 August 2027, this asteroid will pass at about 0.00261abbr=onNaNabbr=on of the Earth's center. During the close approach, it is expected to peak at about apparent magnitude 7.3, and will be visible in binoculars.
has a well-determined orbit with an observation arc of 65 years. It was found by Andreas Doppler and Arno Gnädig in precovery images from 1955. When astronomers had an observation arc of the object of 123 days, computations gave a 1 in 10 million chance it would return on an impact trajectory in 2039.
On 7 August 1946, the asteroid passed 0.00625abbr=onNaNabbr=on from Earth and then 0.00404abbr=onNaNabbr=on from the Moon.
