Key Facts

Overview

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

Kida orbits the sun every 2,060 days (5.64 years), coming as close as 2.78 AU and reaching as far as 3.56 AU from the sun. Kida is about 19.4 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the city of Denver.

The rotation of Kida has been observed. It completes a rotation on its axis every 259.46 hours.

No Close Approaches

Kida'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

Kida's orbit is determined by observations dating back to Oct. 13, 1950. It was last officially observed on July 4, 2023. The IAU Minor Planet Center records 3,701 observations used to determine its orbit.

Accessibility and Exploration

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