  In this paper we perform an assessment of the 2880 Earth impact risk for
asteroid (29075) 1950 DA. To obtain reliable predictions we analyze the
contribution of the observational dataset and the astrometric treatment, the
numerical error in the long-term integration, and the different accelerations
acting on the asteroid. The main source of uncertainty is the Yarkovsky effect,
which we statistically model starting from 1950 DA's available physical
characterization, astrometry, and dynamical properties. Before the release of
2012 radar data, this modeling suggests that 1950 DA has 99% likelihood of
being a retrograde rotator. By using a 7-dimensional Monte Carlo sampling we
map 1950 DA's uncertainty region 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.
