Overview

141498 (2002 EZ16) is a small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 2002 EZ16 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 EZ16 orbits the sun every 323 days (0.88 years), coming as close as 0.40 AU and reaching as far as 1.44 AU from the sun. Based on its brightness and the way it reflects light, 2002 EZ16 is probably between 0.555 to 1.242 kilometers in diameter, making it small in absolute terms, but larger than ~97% of asteroids, very roughly comparable in size to the Golden Gate Bridge.

Close Approaches

2002 EZ16's orbit is 0.18 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.

2002 EZ16 has 8 close approaches predicted in the coming decades:
