We have been looking for a "missing" objects for a while. The nemesis star theory says the sun has a brown dwarf companion. This object would interact with the Oort Cloud instead of the Kuiper belt. But this theory has been pretty much refuted. This theory definitely looks more promising. Finding eccentric Kuiper belt objects, and aligning them with a missing object seems to be a good bet. Giving the object an orbit should make the search easier, and we will probably have a conclusion one way or another within a few years. https://en.wikipedia.org/wiki/Nemesis_(hypothetical_star) https://en.wikipedia.org/wiki/Nemesis_(hypothetical_star)
