Key Facts

Overview

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

Cragg orbits the sun every 1,930 days (5.28 years), coming as close as 2.86 AU and reaching as far as 3.21 AU from the sun. Cragg is about 13.8 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the city of Cleveland, Ohio.

No Close Approaches

Cragg's orbit is 1.87 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

Cragg's orbit is determined by observations dating back to Nov. 30, 1953. It was last officially observed on Feb. 19, 2023. The IAU Minor Planet Center records 3,447 observations used to determine its orbit.

Accessibility and Exploration

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