2020 HO5 is a very small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 2020 HO5 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.
2020 HO5 orbits the sun every 363 days (0.99 years), coming as close as 0.97 AU and reaching as far as 1.02 AU from the sun. Based on its brightness and the way it reflects light, 2020 HO5 is probably between 0.036 to 0.160 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.
2020 HO5's orbit is 0.00 AU from Earth's orbit at its closest point. This means that its orbit is relatively close to Earth's orbit.
2020 HO5 has 18 close approaches predicted in the coming decades:

2020 HO5's orbit is determined by observations dating back to April 23, 2020. It was last officially observed on April 26, 2020. The IAU Minor Planet Center records 47 observations used to determine its orbit.
2020 HO5 can be reached with a journey of 362 days. This trajectory would require a delta-v of 3.874 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 1,061,397 potential trajectories and launch windows to this asteroid.
