Key Facts

Overview

AMOS is a large asteroid that orbits between Mars and Jupiter in the outer reaches of the main asteroid belt. NASA JPL has not classified AMOS as potentially hazardous because its orbit does not bring it close to Earth.

AMOS orbits the sun every 2,800 days (7.67 years), coming as close as 3.78 AU and reaching as far as 4.00 AU from the sun. AMOS is about 49.9 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the U.S. state of Rhode Island.

The rotation of AMOS has been observed. It completes a rotation on its axis every 29.13 hours.

No Close Approaches

AMOS's orbit is 2.78 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

AMOS's orbit is determined by observations dating back to Jan. 8, 1981. It was last officially observed on Jan. 18, 2021. The IAU Minor Planet Center records 2,310 observations used to determine its orbit.

Accessibility and Exploration

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