2020 XY4 is a very small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 2020 XY4 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 XY4 orbits the sun every 293 days (0.80 years), coming as close as 0.56 AU and reaching as far as 1.16 AU from the sun. Based on its brightness and the way it reflects light, 2020 XY4 is probably between 0.007 to 0.031 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.
The rotation of 2020 XY4 has been observed. It completes a rotation on its axis every 0.09 hours.
2020 XY4'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 XY4 has 17 close approaches predicted in the coming decades:

2020 XY4's orbit is determined by observations dating back to Dec. 11, 2020. It was last officially observed on Dec. 21, 2020. The IAU Minor Planet Center records 75 observations used to determine its orbit.
2020 XY4 can be reached with a journey of 370 days. This trajectory would require a delta-v of 10.775 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 3,385 potential trajectories and launch windows to this asteroid.
