- cgriswald 8y agoYes, but I don’t see how that is relevant. Your claim is that we aren’t seeing Jupiter/Earth type systems and so they are rare. The counterargument is that we aren’t looking for them, so we don’t see them. We don’t know whether they are rare or not.
- sliken 8y agoKeep in mind that there's many more orbits that don't occlude a star than those that do. So there's some luck required, and likely at least 2 orbital occlusions (22 years) to be sure.
