Overview
89830 (2002 CE) is a mid-sized asteroid whose orbit approaches the orbit of Earth but does not cross it. NASA JPL has classified 2002 CE as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.
2002 CE orbits the sun every 1,090 days (2.98 years), coming as close as 1.02 AU and reaching as far as 3.13 AU from the sun. 2002 CE is about 5.1 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the San Francisco Bay.
The rotation of 2002 CE has been observed. It completes a rotation on its axis every 2.61 hours.
No Close Approaches
2002 CE's orbit is 0.03 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.
Orbital simulations conducted by NASA JPL's CNEOS do not show any close approaches to Earth.
Images and Observations
2002 CE's orbit is determined by observations dating back to May 25, 1982. It was last officially observed on May 8, 2023. The IAU Minor Planet Center records 2,686 observations used to determine its orbit.
