When a comet or an asteroid gets very close to the sun, it can happen that solar gravity gives it a push that makes it gain speed and shoot out of the solar system, thus becoming an interstellar object whose origin is the solar system Claro this.

The history of the hunt for interstellar objects has an initial moment, a golden moment, in 2017 when the interstellar object called Oumuamua was located, this object is not very large, it is about 230 meters long but only 35 meters wide, it was supposes that it came from beyond the solar system because of the speed at which it arrived, for the sun or a planet to capture an object it needs that object travel at an adequate speed, if it goes very slowly the gravity of the sun can end up attracting it or if It goes very fast, what would happen is that this object would pass by and that is what is happening with Oumuamua, which is currently moving away from the sun rapidly, although it will still take many years to leave the solar system.

So they thought it was a rock and maybe a rock with a lot of metals or even a basically metallic object, because normally very elongated asteroids like this case are identified with metallic asteroids astronomers know this because to maintain the elongated shape they have to be objects very solid and resistant, if it were a rocky object or made up of piles of rocks it would end up breaking after a while with the turns it gives, so astronomers thought it was a fairly dry metallic object, but when it began to move away from the sun , it began to do something strange, it accelerated, it is not that it accelerated, but it was an acceleration that could not be explained with a trajectory dominated by the forces of gravity, there was something even small that was driving it.
