Key Facts

Overview

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

Ozenuma orbits the sun every 1,780 days (4.87 years), coming as close as 2.66 AU and reaching as far as 3.08 AU from the sun. Based on its brightness and the way it reflects light, Ozenuma is probably between 8.761 to 19.590 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the city of Cleveland, Ohio.

No Close Approaches

Ozenuma's orbit is 1.65 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

Ozenuma's orbit is determined by observations dating back to July 16, 1974. It was last officially observed on July 2, 2023. The IAU Minor Planet Center records 3,858 observations used to determine its orbit.

Accessibility and Exploration

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