Key Facts

Overview

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

Amedee orbits the sun every 1,770 days (4.85 years), coming as close as 2.51 AU and reaching as far as 3.23 AU from the sun. Amedee is about 10.8 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the city of Boston.

No Close Approaches

Amedee's orbit is 1.55 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

Amedee's orbit is determined by observations dating back to Dec. 6, 1993. It was last officially observed on April 9, 2023. The IAU Minor Planet Center records 3,018 observations used to determine its orbit.

Accessibility and Exploration

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