Key Facts

Overview

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

Awaji orbits the sun every 1,750 days (4.79 years), coming as close as 2.76 AU and reaching as far as 2.92 AU from the sun. Based on its brightness and the way it reflects light, Awaji is probably between 9.132 to 20.419 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the city of Cleveland, Ohio.

No Close Approaches

Awaji's orbit is 1.78 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

Awaji's orbit is determined by observations dating back to April 2, 1940. It was last officially observed on July 3, 2023. The IAU Minor Planet Center records 3,892 observations used to determine its orbit.

Accessibility and Exploration

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