Overview

2022 HE is a very small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 2022 HE 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 HE orbits the sun every 239 days (0.65 years), coming as close as 0.30 AU and reaching as far as 1.21 AU from the sun. Based on its brightness and the way it reflects light, 2022 HE is probably between 0.093 to 0.209 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.

Close Approaches

2022 HE's orbit is 0.06 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 HE has 23 close approaches predicted in the coming decades:
