Overview

2007 DY40 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2007 DY40 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2007 DY40 orbits the sun every 823 days (2.25 years), coming as close as 0.70 AU and reaching as far as 2.74 AU from the sun. Based on its brightness and the way it reflects light, 2007 DY40 is probably between 0.160 to 0.358 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a football field.

Close Approaches

2007 DY40's orbit is 0.03 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.

2007 DY40 has 7 close approaches predicted in the coming decades:
