Key Facts

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 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 EZ16 has been observed. It completes a rotation on its axis every 5.02 hours.

No 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.

Orbital simulations conducted by NASA JPL's CNEOS do not show any close approaches to Earth.

Images and Observations

2002 EZ16's orbit is determined by observations dating back to Dec. 1, 1995. It was last officially observed on Dec. 8, 2020. The IAU Minor Planet Center records 403 observations used to determine its orbit.

Accessibility and Exploration

This asteroid is not considered a viable target for human exploration by the NHATS study.
