Overview

264357 (2000 AZ93) is a very small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 2000 AZ93 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2000 AZ93 orbits the sun every 236 days (0.65 years), coming as close as 0.48 AU and reaching as far as 1.02 AU from the sun. 2000 AZ93 is about 0.1 kilometers in diameter, making it a small to average asteroid, comparable in size to a school bus or smaller.

Close Approaches

2000 AZ93's orbit is 0.02 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.

2000 AZ93 has 28 close approaches predicted in the coming decades:
