Overview

2022 HC2 is a very small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 2022 HC2 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 HC2 orbits the sun every 326 days (0.89 years), coming as close as 0.79 AU and reaching as far as 1.07 AU from the sun. Based on its brightness and the way it reflects light, 2022 HC2 is probably between 0.018 to 0.081 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.

Close Approaches

2022 HC2's orbit is 0.05 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 HC2 has 29 close approaches predicted in the coming decades:

Images and Observations

2022 HC2's orbit is determined by observations dating back to April 25, 2022. It was last officially observed on May 11, 2022. The IAU Minor Planet Center records 77 observations used to determine its orbit.

Accessibility and Exploration

2022 HC2 can be reached with a journey of 362 days. This trajectory would require a delta-v of 8.301 km/s. To put this into perspective, the delta-v to launch a rocket to Low-Earth Orbit is 9.7 km/s. There are 52,464 potential trajectories and launch windows to this asteroid.
