Overview

141495 (2002 EZ11) is a small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2002 EZ11 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2002 EZ11 orbits the sun every 430 days (1.18 years), coming as close as 0.22 AU and reaching as far as 2.01 AU from the sun. Its orbit is highly elliptical. Based on its brightness and the way it reflects light, 2002 EZ11 is probably between 0.538 to 1.202 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.

The rotation of 2002 EZ11 has been observed. It completes a rotation on its axis every 2.33 hours.

Close Approaches

2002 EZ11's orbit is 0.00 AU from Earth's orbit at its closest point. This means that its orbit is very close to Earth's orbit.

2002 EZ11 has 25 close approaches predicted in the coming decades:
