Key Facts

Overview

Kodaira is a mid-sized asteroid with an orbit that crosses the orbit of Mars. NASA JPL has not classified Kodaira as potentially hazardous because its orbit does not bring it close to Earth.

Kodaira orbits the sun every 1,670 days (4.57 years), coming as close as 1.60 AU and reaching as far as 3.91 AU from the sun. Kodaira is about 9.5 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the San Francisco Bay.

The rotation of Kodaira has been observed. It completes a rotation on its axis every 5.40 hours.

Kodaira's spectral type None (Tholen) / B (SMASSII) indicates that it is likely to contain hydrogen, nitrogen, ammonia, and iron.

No Close Approaches

Kodaira's orbit is 0.82 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

Kodaira's orbit is determined by observations dating back to April 11, 1970. It was last officially observed on June 30, 2023. The IAU Minor Planet Center records 2,662 observations used to determine its orbit.

Accessibility and Exploration

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