Overview
483422 (2000 CE59) is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2000 CE59 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.
2000 CE59 orbits the sun every 443 days (1.21 years), coming as close as 0.95 AU and reaching as far as 1.33 AU from the sun. Based on its brightness and the way it reflects light, 2000 CE59 is probably between 0.136 to 0.609 kilometers in diameter, making it larger than 90% of asteroids but tiny compared to large asteroids, very roughly comparable in size to the U.S. Capitol building.
The rotation of 2000 CE59 has been observed. It completes a rotation on its axis every 3.62 hours.
2000 CE59's spectral type None (Tholen) / L (SMASSII) indicates that it is likely to contain magnesium silicate, iron silicate, and aluminum.
Close Approaches
2000 CE59'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.
2000 CE59 has 17 close approaches predicted in the coming decades:

Images and Observations
2000 CE59's orbit is determined by observations dating back to Feb. 4, 2000. It was last officially observed on Jan. 29, 2023. The IAU Minor Planet Center records 395 observations used to determine its orbit.
Accessibility and Exploration
2000 CE59 can be reached with a journey of 370 days. This trajectory would require a delta-v of 10.39 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 583 potential trajectories and launch windows to this asteroid.
