Key Facts

Overview

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

Aposhanskij orbits the sun every 1,900 days (5.20 years), coming as close as 2.67 AU and reaching as far as 3.33 AU from the sun. Based on its brightness and the way it reflects light, Aposhanskij is probably between 6.435 to 14.389 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the San Francisco Bay.

No Close Approaches

Aposhanskij's orbit is 1.66 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

Aposhanskij's orbit is determined by observations dating back to April 16, 1955. It was last officially observed on June 10, 2023. The IAU Minor Planet Center records 2,970 observations used to determine its orbit.

Accessibility and Exploration

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