2020 KZ2 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2020 KZ2 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 KZ2 orbits the sun every 373 days (1.02 years), coming as close as 0.98 AU and reaching as far as 1.05 AU from the sun. Based on its brightness and the way it reflects light, 2020 KZ2 is probably between 0.005 to 0.022 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.
2020 KZ2's orbit is 0.01 AU from Earth's orbit at its closest point. This means that its orbit is relatively close to Earth's orbit.
2020 KZ2 has 26 close approaches predicted in the coming decades:

2020 KZ2's orbit is determined by observations dating back to May 20, 2020. It was last officially observed on May 28, 2020. The IAU Minor Planet Center records 39 observations used to determine its orbit.
2020 KZ2 can be reached with a journey of 362 days. This trajectory would require a delta-v of 4.508 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 727,779 potential trajectories and launch windows to this asteroid.
