Overview

413989 (2007 EL88) is a small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2007 EL88 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2007 EL88 orbits the sun every 433 days (1.19 years), coming as close as 0.54 AU and reaching as far as 1.70 AU from the sun. Based on its brightness and the way it reflects light, 2007 EL88 is probably between 0.408 to 0.912 kilometers in diameter, making it larger than ~97% of asteroids but small compared to large asteroids, very roughly comparable in size to the Golden Gate Bridge.

Close Approaches

2007 EL88'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 EL88 has 12 close approaches predicted in the coming decades:
