Key Facts

Overview

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

Kamuimintara orbits the sun every 1,950 days (5.34 years), coming as close as 2.78 AU and reaching as far as 3.33 AU from the sun. Kamuimintara is about 14.5 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the city of Cleveland, Ohio.

The rotation of Kamuimintara has been observed. It completes a rotation on its axis every 4.93 hours.

No Close Approaches

Kamuimintara's orbit is 1.79 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

Kamuimintara's orbit is determined by observations dating back to Oct. 27, 1973. It was last officially observed on June 16, 2023. The IAU Minor Planet Center records 3,568 observations used to determine its orbit.

Accessibility and Exploration

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