Key Facts

  • Categorized as a Main-belt Asteroid
  • Comparable in size to the U.S. state of Connecticut (118.93 km diameter)
  • Not a Near Earth Object
  • Not a Potentially Hazardous Object
  • See orbit simulation

Overview

Chloris is a large asteroid orbiting between Mars and Jupiter in the main portion of the asteroid belt. NASA JPL has not classified Chloris as potentially hazardous because its orbit does not bring it close to Earth.

Chloris orbits the sun every 1,640 days (4.49 years), coming as close as 2.07 AU and reaching as far as 3.38 AU from the sun. Chloris is about 118.9 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the U.S. state of Connecticut.

The rotation of Chloris has been observed. It completes a rotation on its axis every 32.50 hours.

Chloris's spectral type C (Tholen) / Ch (SMASSII) indicates that it is likely to contain water, iron, nickel, cobalt, nitrogen, and ammonia.

No Close Approaches

Chloris's orbit is 1.05 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

Chloris's orbit is determined by observations dating back to April 13, 1906. It was last officially observed on July 4, 2023. The IAU Minor Planet Center records 7,044 observations used to determine its orbit.

Accessibility and Exploration

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