Overview

2022 AY1 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2022 AY1 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2022 AY1 orbits the sun every 476 days (1.30 years), coming as close as 0.91 AU and reaching as far as 1.48 AU from the sun. Based on its brightness and the way it reflects light, 2022 AY1 is probably between 0.105 to 0.236 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a basketball court.

Close Approaches

2022 AY1's orbit is 0.00 AU from Earth's orbit at its closest point. This means that its orbit is relatively close to Earth's orbit.

2022 AY1 has 12 close approaches predicted in the coming decades:
