Key Facts

Overview

8350 (1989 AG) is a large asteroid orbiting between Mars and Jupiter in the main portion of the asteroid belt. NASA JPL has not classified 1989 AG as potentially hazardous because its orbit does not bring it close to Earth.

1989 AG orbits the sun every 1,590 days (4.35 years), coming as close as 2.29 AU and reaching as far as 3.04 AU from the sun. 1989 AG is about 11.9 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the city of Cleveland, Ohio.

The rotation of 1989 AG has been observed. It completes a rotation on its axis every 5.05 hours.

No Close Approaches

1989 AG's orbit is 1.32 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

1989 AG's orbit is determined by observations dating back to Dec. 18, 1979. It was last officially observed on Feb. 17, 2023. The IAU Minor Planet Center records 3,643 observations used to determine its orbit.

Accessibility and Exploration

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