Key Facts

• Categorized as a Main-belt Asteroid
• Comparable in size to the city of Cleveland, Ohio (12.78 km diameter)
• Not a Near Earth Object
• Not a Potentially Hazardous Object
• See orbit simulation

Overview

18889 (2000 CC28) is a large asteroid orbiting between Mars and Jupiter in the main portion of the asteroid belt. NASA JPL has not classified 2000 CC28 as potentially hazardous because its orbit does not bring it close to Earth.

2000 CC28 orbits the sun every 1,580 days (4.33 years), coming as close as 2.29 AU and reaching as far as 3.01 AU from the sun. 2000 CC28 is about 12.8 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the city of Cleveland, Ohio.

The rotation of 2000 CC28 has been observed. It completes a rotation on its axis every 20.73 hours.

No Close Approaches

2000 CC28's orbit is 1.33 AU from Earth's orbit at its closest point. This means that there is an extremely 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.
