Overview

325102 (2008 EY5) is a very small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 2008 EY5 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.

2008 EY5 orbits the sun every 181 days (0.50 years), coming as close as 0.23 AU and reaching as far as 1.02 AU from the sun. 2008 EY5 is about 0.4 kilometers in diameter, making it small in absolute terms, but larger than 90% of asteroids, comparable in size to the U.S. Capitol building.

Close Approaches

2008 EY5's orbit is 0.08 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.

2008 EY5 has 47 close approaches predicted in the coming decades:
