Key Facts
- Categorized as a Mars-crossing Asteroid
- Comparable in size to Mount Everest (1.80 km diameter)
- Not a Near Earth Object
- Not a Potentially Hazardous Object
- See orbit simulation
Overview
Duke is a mid-sized asteroid with an orbit that crosses the orbit of Mars. NASA JPL has not classified Duke as potentially hazardous because its orbit does not bring it close to Earth.
Duke orbits the sun every 945 days (2.59 years), coming as close as 1.66 AU and reaching as far as 2.11 AU from the sun. Duke is about 1.8 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to Mount Everest.
The rotation of Duke has been observed. It completes a rotation on its axis every 13.94 hours.
No Close Approaches
Duke's orbit is 0.78 AU from Earth's orbit at its closest point. This means that there is a very 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
Duke's orbit is determined by observations dating back to Oct. 20, 1992. It was last officially observed on June 30, 2023. The IAU Minor Planet Center records 2,585 observations used to determine its orbit.
Accessibility and Exploration
This asteroid is not considered a viable target for human exploration by the NHATS study.Similar Objects
