  • Not a Near Earth Object
  • Not a Potentially Hazardous Object
  • See orbit simulation

Overview

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

Pandarus orbits the sun every 4,330 days (11.85 years), coming as close as 4.84 AU and reaching as far as 5.56 AU from the sun. Pandarus is about 74.3 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the U.S. state of Delaware.

The rotation of Pandarus has been observed. It completes a rotation on its axis every 8.48 hours.

Pandarus's spectral type D (Tholen) / None (SMASSII) indicates that it is likely to contain .

No Close Approaches

Pandarus's orbit is 3.83 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

Pandarus's orbit is determined by observations dating back to April 14, 1972. It was last officially observed on July 4, 2023. The IAU Minor Planet Center records 3,703 observations used to determine its orbit.

Accessibility and Exploration

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