Key Facts

Overview

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

Miyazawakenji orbits the sun every 1,200 days (3.29 years), coming as close as 2.08 AU and reaching as far as 2.35 AU from the sun. Miyazawakenji is about 7.2 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the San Francisco Bay.

The rotation of Miyazawakenji has been observed. It completes a rotation on its axis every 17.40 hours.

Miyazawakenji's spectral type None (Tholen) / S (SMASSII) indicates that it is likely to contain and .

No Close Approaches

Miyazawakenji's orbit is 1.08 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

Miyazawakenji's orbit is determined by observations dating back to July 28, 1949. It was last officially observed on March 13, 2023. The IAU Minor Planet Center records 3,802 observations used to determine its orbit.
