Overview

137924 (2000 BD19) is a small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 2000 BD19 as a "Near Earth Asteroid" due to its orbit's proximity to Earth, but it is not considered potentially hazardous because computer simulations have not indicated any imminent likelihood of future collision.

2000 BD19 orbits the sun every 300 days (0.82 years), coming as close as 0.09 AU and reaching as far as 1.66 AU from the sun. Its orbit is highly elliptical. 2000 BD19 is about 1.0 kilometers in diameter, making it small in absolute terms, but larger than ~97% of asteroids, comparable in size to the Golden Gate Bridge.

The rotation of 2000 BD19 has been observed. It completes a rotation on its axis every 10.57 days.

Close Approaches

2000 BD19's orbit is 0.09 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.

2000 BD19 has 15 close approaches predicted in the coming decades:
