Key Facts

Overview

Amycus is a average-sized asteroid with an orbit between Jupiter and Neptune. NASA JPL has not classified Amycus as potentially hazardous because its orbit does not bring it close to Earth.

Amycus orbits the sun every 46,256 days (126.64 years), coming as close as 15.25 AU and reaching as far as 35.18 AU from the sun. Amycus is about 100.9 kilometers in diameter, making it larger than most asteroids, comparable in size to the U.S. state of Delaware.

The rotation of Amycus has been observed. It completes a rotation on its axis every 9.76 days.

No Close Approaches

Amycus's orbit is 14.28 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

Amycus's orbit is determined by observations dating back to Nov. 24, 1987. It was last officially observed on Aug. 15, 2007. The IAU Minor Planet Center records 76 observations used to determine its orbit.

Accessibility and Exploration

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