>>13067893- Space is big, really big
- Its on a 10-20,000 year orbit; so we don't really know where to look
- It's crazy crazy far away, so light reflection, is extremely low
- observatory upmass capability is lower than the lowest a jenga bar can go; which massively limits throwing probes out there or putting observatories out to look into the area the planet is suspected to be in explicitly and only for that for the entire life of the observatory
- there's thousands upon thousands of applications of observatory time and not enough capacity
Either, we need the ability to put up the equivalent of JWST but in visible spectrum or visible and IR and point it to where this planet is expected to be (general region) and then collect data for like 5 years nonstop and look at nothing else or we need the ability to throw a hundred or so probes in a cone of that area with laser links and repeaters going back to Earth space so that we can do real time tracking/repositioning to look at all areas within the cone for it.
EITHER WAY, it requires launch capabilities we don't have and won't have for another 10-15 years. By that time, we'll find it by sheer luck or it'll take another 20 years, give or take post launch upmass capability, to put up an observatory that can find it.
