Overview
2022 HB is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2022 HB as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.
2022 HB orbits the sun every 401 days (1.10 years), coming as close as 0.66 AU and reaching as far as 1.47 AU from the sun. Based on its brightness and the way it reflects light, 2022 HB is probably between 0.109 to 0.243 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a basketball court.
The rotation of 2022 HB has been observed. It completes a rotation on its axis every 86.60 hours.
Close Approaches
2022 HB'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.
2022 HB has 24 close approaches predicted in the coming decades:
