Overview

29075 (1950 DA) is a mid-sized asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 1950 DA as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

1950 DA orbits the sun every 809 days (2.21 years), coming as close as 0.84 AU and reaching as far as 2.56 AU from the sun. 1950 DA is about 2.0 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to Mount Everest.

The rotation of 1950 DA has been observed. It completes a rotation on its axis every 2.12 hours.

Close Approaches

1950 DA's orbit is 0.04 AU from Earth's orbit at its closest point. This means that there is an wide berth between this asteroid and Earth at all times.

1950 DA has 5 close approaches predicted in the coming decades:

Date Distance from Earth (km) Velocity (km/s)
March 2, 2032 11,332,558 15.580
March 19, 2074 14,280,690 12.090
March 10, 2105 5,432,850 13.803
March 11, 2136 6,372,032 13.356
March 8, 2187 5,270,438 14.299

NASA Sentry has assessed impact risk for 1 very close approach scenarios. Here are the top scenarios ordered by probability of impact:

Date Distance from Earth (km) Distance Error (km) Probability of Impact (%) Impact Energy (Mt)
March 16, 2880 237.54 ±6.42 0.01200 75380.0
