Key Facts

Overview

Chrisclark is a large asteroid that orbits between Mars and Jupiter in the outer reaches of the main asteroid belt. NASA JPL has not classified Chrisclark as potentially hazardous because its orbit does not bring it close to Earth.

Chrisclark orbits the sun every 2,100 days (5.75 years), coming as close as 2.76 AU and reaching as far as 3.65 AU from the sun. Chrisclark is about 19.1 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the city of Philadelphia.

The rotation of Chrisclark has been observed. It completes a rotation on its axis every 10.97 hours.

No Close Approaches

Chrisclark's orbit is 1.83 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

Chrisclark's orbit is determined by observations dating back to Sept. 7, 1954. It was last officially observed on Nov. 22, 2022. The IAU Minor Planet Center records 2,654 observations used to determine its orbit.

Accessibility and Exploration

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