Overview

2023 KM5 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2023 KM5 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2023 KM5 orbits the sun every 470 days (1.29 years), coming as close as 0.99 AU and reaching as far as 1.37 AU from the sun. Based on its brightness and the way it reflects light, 2023 KM5 is probably between 0.165 to 0.370 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a football field.

Close Approaches

2023 KM5's orbit is 0.03 AU from Earth's orbit at its closest point. This means that there is a wide berth between this asteroid and Earth at all times.

2023 KM5 has 11 close approaches predicted in the coming decades:
