Agamemnon is a large asteroid that shares Jupiter's orbit around the sun. NASA JPL has not classified Agamemnon as potentially hazardous because its orbit does not bring it close to Earth.
Agamemnon orbits the sun every 4,430 days (12.13 years), coming as close as 4.92 AU and reaching as far as 5.64 AU from the sun. Agamemnon is about 131.0 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the U.S. state of Connecticut.
The rotation of Agamemnon has been observed. It completes a rotation on its axis every 6.59 hours.
Agamemnon's spectral type D (Tholen) / None (SMASSII) indicates that it is likely to contain .
Agamemnon's orbit is 4.02 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.
Agamemnon's orbit is determined by observations dating back to March 19, 1919. It was last officially observed on Nov. 8, 2022. The IAU Minor Planet Center records 3,513 observations used to determine its orbit.
