Key Facts

Overview

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

Chaka orbits the sun every 1,550 days (4.24 years), coming as close as 1.81 AU and reaching as far as 3.43 AU from the sun. Chaka is about 17.6 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the city of Philadelphia.

The rotation of Chaka has been observed. It completes a rotation on its axis every 25.46 hours.

No Close Approaches

Chaka's orbit is 0.84 AU from Earth's orbit at its closest point. This means that there is a very 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

Chaka's orbit is determined by observations dating back to July 4, 1932. It was last officially observed on May 15, 2023. The IAU Minor Planet Center records 3,584 observations used to determine its orbit.

Accessibility and Exploration

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