Looking for Lurkers: Co-Orbiters as SETI Observables
- Kaibeezy 7y agohttps://arxiv.org/ftp/arxiv/papers/1903/1903.09582.pdf https://arxiv.org/ftp/arxiv/papers/1903/1903.09582.pdf Abstract: A recently discovered group of nearby co-orbital objects is an attractive location for extraterrestrial intelligence (ETI) to locate a probe to observe Earth while not being easily seen. These near-Earth objects provide an ideal way to watch our world from a secure natural object. That provides resources an ETI might need: materials, a firm anchor, and concealment. These have been little studied by astronomy and not at all by the Search for Extraterrestrial Intelligence (SETI) or planetary radar observations. I describe the objects found thus far and propose both passive and active observations of them as possible sites for extraterrestrial (ET) probes.
