Key Facts

  • Categorized as a Jupiter Trojan
  • Comparable in size to the U.S. state of Rhode Island (63.19 km diameter)
  • Not a Near Earth Object
  • Not a Potentially Hazardous Object
  • See orbit simulation

Overview

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

Charops orbits the sun every 4,270 days (11.69 years), coming as close as 4.49 AU and reaching as far as 5.80 AU from the sun. Charops is about 63.2 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the U.S. state of Rhode Island.

The rotation of Charops has been observed. It completes a rotation on its axis every 20.24 hours.

No Close Approaches

Charops's orbit is 3.48 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

Charops's orbit is determined by observations dating back to Sept. 27, 1954. It was last officially observed on July 4, 2023. The IAU Minor Planet Center records 3,132 observations used to determine its orbit.

Accessibility and Exploration

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