 A concurring diameter estimate of kilometers from an occultation event "(see below)" has also been obtained.The "Collaborative Asteroid Lightcurve Link" agrees with the results obtained by IRAS, that is, an albedo of 0.0444 and a diameter of 166.66 kilometers based on an absolute magnitude of 7.89.A 2012 occultation produced a 2D shape model of roughly (with an irregular, skewed outline) and are suggestive of "Agamemnon" to have a satellite of approximately kilometers in diameter orbiting at from the primary's center.
