Oumuamua, the first interstellar object zipped through the solar system in October 2017. Its closet distance from earth was 20.5 million miles and when it was observed, the interstellar object was traveling at a speed of 67,100 miles per hour. Since that day, the scientists have been investigating the object. Now, the new study shows that Oumuamua had come from a binary star system. The new research has been published in the journal Monthly Notices of the Royal Astronomical Society. The study also suggested that the star system where Oumuamua arose was young and that star system still in the process of forming planets.

Talking about this, Dr. Alan Jackson, from University of Toronto and the lead author of the study stated, “It is remarkable we have now seen the first time a physical object from outside our solar system.” Jackson and his team used computer models to detect the objects that come from binary than single star systems. The reason behind this might be the strong gravitational fields produced by binaries. Oumuamua likely came from a system which may contain hot, high mass star and have a large number of the rocky object closer in.

Jackson further stated, “We simulated 2,000 binary stars on a computer and put a small body in orbit around each binary.” After that, they gradually moved the orbit of the small body closer to the binary. Previously they have been found that the object’s orbit becomes unstable when it comes closer the central binary and the small object is ejected from the system. There are many star system which can fling objects into space and many of them include more than two stellar objects. The study further informed that binary systems can pitch asteroids and comets into interstellar space in equal proportions. Maybe the next interstellar object will be a comet.
