Overview

2022 BA is a very small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 2022 BA as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2022 BA orbits the sun every 265 days (0.73 years), coming as close as 0.48 AU and reaching as far as 1.13 AU from the sun. Based on its brightness and the way it reflects light, 2022 BA is probably between 0.142 to 0.318 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a football field.

Close Approaches

2022 BA'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 BA has 16 close approaches predicted in the coming decades:
