Overview

2016 DL is a very small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 2016 DL as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2016 DL orbits the sun every 220 days (0.60 years), coming as close as 0.38 AU and reaching as far as 1.05 AU from the sun. 2016 DL is about 0.2 kilometers in diameter, making it a small to average asteroid, comparable in size to a football field.

Close Approaches

2016 DL's orbit is 0.05 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.

2016 DL has 23 close approaches predicted in the coming decades:
