[edit] Lost
It appears that Aethra was lost soon after discovery, and is mentioned in a context that implies it was still lost in Proc.Natl.Acad.Sci. v005 p00067 (1919) "Perturbations and Tables of the Minor Planets Discovered by James C. Watson". Evidently it has since been recovered. It seems a safe bet that it's Mars-crossing habits and the perturbations that exercised people for approaching 50 years (or more!) after it's discovery are not unrelated, but I can't find out more with my small store of astronomical knowledge. I'm reasonably sure there's an interesting story to be told here, but I don't have the knowledge to dig it out myself. -- 134.146.0.41 on 27 December 2005
- The original observation arc was only 22 days and the asteroid is highly eccentric due to perturbations by Mars and Jupiter. -- Kheider (talk) 21:49, 22 September 2011 (UTC)
[edit] Why Mars-crosser?
The orbit of 132 Aethra never cross this of Mars: when 132 Aethra go to the perihelion, it is very far out of the orbit of Mars because the orbite of Aethra has very great inclination. --Jean-François Clet (talk) 17:22, 28 July 2010 (UTC)
- JPL lists it as a Mars-crossing Asteroid -- Kheider (talk) 21:49, 22 September 2011 (UTC)
