Key Facts

  • Categorized as a Jupiter Trojan
  • Comparable in size to the city of Houston (36.96 km diameter)
  • Not a Near Earth Object
  • Not a Potentially Hazardous Object
  • See orbit simulation

Overview

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

Eurymedon orbits the sun every 4,410 days (12.07 years), coming as close as 4.81 AU and reaching as far as 5.72 AU from the sun. Eurymedon is about 37.0 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the city of Houston.

The rotation of Eurymedon has been observed. It completes a rotation on its axis every 46.00 hours.

No Close Approaches

Eurymedon's orbit is 3.81 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

Eurymedon's orbit is determined by observations dating back to Feb. 10, 1954. It was last officially observed on April 16, 2023. The IAU Minor Planet Center records 3,027 observations used to determine its orbit.

Accessibility and Exploration

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