(29075) 1950 DA

Template: Infobox Asteroid / Maintenance / Error 2

(29075) 1950 DA is an asteroid that crosses both the orbit of the Earth as well as Mars. 1950 DA was discovered on 23 February 1950 by Carl A. Wirtanen at the Lick Observatory on Mount Hamilton. After the asteroid was observed during 17 days, he was no longer detect.

On 31 December 2000, the object of the sky monitoring LONEOS was rediscovered and received in the meantime the provisional designation 2000 YK66 until it was found that it was around 1950 DA.

With the help of radar observations at Goldstone and Arecibo Observatory has been able to determine the orbit of 1950 DA with very high accuracy. The analysis revealed that 1950 DA earth will come very close on 16 March 2880 and there is even the possibility of a collision with Earth, the center of the Atlantic was calculated as being cut. But the probability is low, it is at most 0.33% (approximately 1 to 300). 1950 DA was 0.17 with the first object for which a value was greater than zero on the Palermo scale. Although in the meantime for other asteroids, a positive value was calculated on the Palermo scale, 1950 DA is currently the only object to which this was granted for a long time.

The radar observations also show that there is a nearly spherical object with a diameter of 1.1 kilometers at 1950 DA. The asteroid rotates in just about two hours around its own axis, that is unusually fast for an object of this size.
