Overview

2022 US5 is a very small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 2022 US5 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.

2022 US5 orbits the sun every 295 days (0.81 years), coming as close as 0.70 AU and reaching as far as 1.03 AU from the sun. Based on its brightness and the way it reflects light, 2022 US5 is probably between 0.012 to 0.028 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.

Close Approaches

2022 US5's orbit is 0.02 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.

2022 US5 has 15 close approaches predicted in the coming decades:
