 | | Were Ganymed a single, peculiar object, this would be plausible; but if 2204 Lyyli and 132 Aethra have also lifetimes as short as 10 (or even 40) Myr, this explanation becomes very unlikely. |
 | | In summary, we conclude that the origin of Ganymed and its siblings is still an open problem, with no straightforward solution at hand. |
