Overview

458116 (2010 DA) is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2010 DA as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2010 DA orbits the sun every 382 days (1.05 years), coming as close as 0.45 AU and reaching as far as 1.61 AU from the sun. Based on its brightness and the way it reflects light, 2010 DA is probably between 0.233 to 0.520 kilometers in diameter, making it larger than 90% of asteroids but tiny compared to large asteroids, very roughly comparable in size to a football field.

Close Approaches

2010 DA's orbit is 0.00 AU from Earth's orbit at its closest point. This means that its orbit is relatively close to Earth's orbit.

2010 DA has 10 close approaches predicted in the coming decades:
