1950 DA
(29075) 1950 DA is a near-Earth asteroid. Among asteroids more than 1 km in diameter, it is notable for having the highest known probability of impacting Earth. In 2002, it had the highest Palermo rating with a value of 0.17 for a possible collision in 2880. Since that time, the estimated risk has been updated several times. In December 2015, the odds of an Earth impact were revised to 1 in 8,330 (0.012%) with a Palermo rating of −1.42. (29075) 1950 DA is not assigned a Torino scale rating, because the 2880 date is over 100 years in the future. (29075) 1950 DA - Wikipedia, the free encyclopedia
