Key Facts

  • Categorized as a Jupiter Trojan
  • Comparable in size to the U.S. state of Rhode Island (64.90 km diameter)
  • Not a Near Earth Object
  • Not a Potentially Hazardous Object
  • See orbit simulation

Overview

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

Telamon orbits the sun every 4,267 days (11.68 years), coming as close as 4.60 AU and reaching as far as 5.70 AU from the sun. Telamon is about 64.9 kilometers in diameter, making it larger than most asteroids, comparable in size to the U.S. state of Rhode Island.

The rotation of Telamon has been observed. It completes a rotation on its axis every 16.98 days.

No Close Approaches

Telamon's orbit is 3.62 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

Telamon's orbit is determined by observations dating back to Sept. 23, 1949. It was last officially observed on Aug. 22, 2019. The IAU Minor Planet Center records 1,878 observations used to determine its orbit.

Accessibility and Exploration

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