Overview

141484 (2002 DB4) is a mid-sized asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 2002 DB4 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.

2002 DB4 orbits the sun every 290 days (0.79 years), coming as close as 0.54 AU and reaching as far as 1.18 AU from the sun. 2002 DB4 is about 1.0 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the Golden Gate Bridge.

Close Approaches

2002 DB4's orbit is 0.15 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.

2002 DB4 has 17 close approaches predicted in the coming decades:
