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 808 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 a 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 | 11,332,532 | 15.580 |
| March 19, 2074 | 14,280,717 | 12.090 |
