The hypothetical "planet 9" that astronomers have been actively searching for during the past several years is expected to orbit somewhere between the Kuiper belt and the Oort cloud โ€” and we absolutely do have the technology to detect it, it's just painstaking work that takes a lot of telescope time (which is in short supply since lots of astronomers are all competing for it) and is difficult to automate.
