Key Facts

  • Categorized as a Jupiter Trojan
  • Comparable in size to the city of Indianapolis (28.96 km diameter)
  • Not a Near Earth Object
  • Not a Potentially Hazardous Object
  • See orbit simulation

Overview

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

Podarkes orbits the sun every 4,310 days (11.80 years), coming as close as 5.12 AU and reaching as far as 5.24 AU from the sun. Podarkes is about 29.0 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the city of Indianapolis.

The rotation of Podarkes has been observed. It completes a rotation on its axis every 245.00 hours.

No Close Approaches

Podarkes's orbit is 4.13 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

Podarkes's orbit is determined by observations dating back to March 22, 1991. It was last officially observed on May 3, 2023. The IAU Minor Planet Center records 2,288 observations used to determine its orbit.

Accessibility and Exploration

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