Based on statistics and computer modeling, some scientists believe that the interstellar object Oumuamau likely came from stellar binary system.

For the new study, published in the journal Monthly Notices of the Royal Astronomical Society, Jackson and his co-authors set about testing how efficient binary star systems are at ejecting objects. They also looked at how common these star systems are in the Galaxy. They found that rocky objects like ‘Oumuamua are far more likely to come from binary than single star systems. They were also able to determine that rocky objects are ejected from binary systems in comparable numbers to icy objects.

Their conclusion does make sense, though any good scientist would retain a gigantic sense of skepticism. While it is statistically reasonable to conclude that a majority of interstellar objects should come from binary systems, there is no guarantee that Oumuamua in particular did so. Even if the odds were one in a million, there is always that one, and the universe often seems prone to fooling us.

    Even if the odds are one in 1 million…
    The odds that object from another solar system would pass so close to our Sun are so great, it is the reason they had to take a good look at it just to make sure that it was a natural object.
    How often do binary stars throw objects at us? It seems to happen too close, too often. Interstellar space must be full of such objects for this phenomenon to occur so frequently.
    The sooner we have an early warning detection system the better.
