It was spotted by the Pan-STARRS1 telescope in Hawaii on October 19 and travelling at about 95,000 kilometres per hour.
Scientists had originally thought that the asteroid originated from the star Vega, which is 25 light years away, but by analysing the trajectory of the rock, they have determined that Vega would have been no where near its current positing 300,000 years ago when Oumuamua’s journey started.
This has led scientists to believe that it has been wandering the Milky Way aimlessly for hundreds of millions of years.
Dr Karen Meech, from the Institute for Astronomy in Hawaii, said: "Oumuamua may well have been wandering through the Milky Way, unattached to any star system, for hundreds of millions of years before its chance encounter with the solar system. "This unusually large variation in brightness means that the object is highly elongated.
Scientists believe that interstellar objects enter our solar system about once a year, but they are difficult to spot because they are so faint.
Analysis of the rock suggests that it has a high metal content, but is lacking in water and ice.
