Key Facts

Overview

David Hughes is a small asteroid with an orbit that crosses the orbit of Mars. NASA JPL has not classified David Hughes as potentially hazardous because its orbit does not bring it close to Earth.

David Hughes orbits the sun every 829 days (2.27 years), coming as close as 1.47 AU and reaching as far as 1.98 AU from the sun. Based on its brightness and the way it reflects light, David Hughes is probably between 3.504 to 7.835 kilometers in diameter, making it larger than most asteroids, very roughly comparable in size to the island of Manhattan.

The rotation of David Hughes has been observed. It completes a rotation on its axis every 24.00 days.

David Hughes's spectral type (Tholen) / Xe (SMASSII) indicates that it is likely to contain nickel, iron, and cobalt.

No Close Approaches

David Hughes's orbit is 0.55 AU from Earth's orbit at its closest point. This means that there is an 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

David Hughes's orbit is determined by observations dating back to June 6, 1980. It was last officially observed on Sept. 15, 2019. The IAU Minor Planet Center records 1,159 observations used to determine its orbit.

Accessibility and Exploration

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