Overview

2022 HL1 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2022 HL1 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 HL1 orbits the sun every 370 days (1.01 years), coming as close as 0.91 AU and reaching as far as 1.11 AU from the sun. Based on its brightness and the way it reflects light, 2022 HL1 is probably between 0.022 to 0.050 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.

Close Approaches

2022 HL1'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 HL1 has 29 close approaches predicted in the coming decades:
