  • Not a Potentially Hazardous Object
  • See orbit simulation

Overview

39287 (2001 CD14) is a large asteroid that shares Jupiter's orbit around the sun. NASA JPL has not classified 2001 CD14 as potentially hazardous because its orbit does not bring it close to Earth.

2001 CD14 orbits the sun every 4,220 days (11.55 years), coming as close as 4.89 AU and reaching as far as 5.33 AU from the sun. 2001 CD14 is about 13.1 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the city of Cleveland, Ohio.

No Close Approaches

2001 CD14's orbit is 3.90 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.

Images and Observations

2001 CD14's orbit is determined by observations dating back to March 14, 1991. It was last officially observed on Jan. 28, 2023. The IAU Minor Planet Center records 776 observations used to determine its orbit.

Accessibility and Exploration

This asteroid is not considered a viable target for human exploration by the NHATS study.
