Assessment of 2880 impact threat from asteroid (29075) 1950 DA D. Farnocchia, S.R. Chesley By using a 7-dimensional Monte Carlo sampling, 1950 DAs uncertainty region was mapped to the 2880 close approach b-plane and find a 5 x 10^-4 impact probability. With the recently released 2012 radar observations, the direct rotation is definitely ruled out and the impact probability decreases to 2.5 x 10^-4. The main source of uncertainty is the Yarkovsky effect. arxiv.org/abs/1310.0861
