If the scientists can find out detail on that object then this will be the first outer solar system object to be observed and confirmed by the astronomers, NASA stated.
A visitor from interstellar space has likely been spotted in our solar system for the first time ever.
Their findings suggest that it is a small rocky or icy object that may have been drifting through our galaxy for millions or even billions of years, before entering our solar system by chance. "It didn't move like comets or asteroids normally do", says astronomer Rob Weryk at the University of Hawaii at Manoa, who first noticed the object on the morning of 19 October. It is believed that the object was from another star system.

He immediately contacted IFA graduates Marco Micheli, who had detected the same thing in the images that were taken at the European Space Agency's telescope on Tenerife in the Canary Islands. According to experts, it's less than a quarter-mile in diameter and is speeding through space at 15.8 miles per second.
"We have been waiting for this day for decades", said CNEOS Manager Paul Chodas.
It's not a threat to Earth, scientists say.
The object approached our solar system from nearly directly "above" the ecliptic, the plane in space near where the planets and most asteroids orbit the Sun, so it did not have any close encounters with the eight major planets during its plunge toward the Sun.
On September 2, it traversed the elliptic plane inside Mercury's orbit. Tweaked by Sun's gravity it beck pedaled course and bolted back above the elliptic at an angle, passing about 15 million miles from Earth on October 14. The general observation is that the object is heading towards the constellation Pegasus, and is on its way out. Astronomers believe that it may be thrown out of other star systems during the period of planet formation.
Since this is the first of its kind, naming the object may need new guidelines from the International Astronomical Union.
Scientists hope to use the data collected while tracking A/2017 U1 to confirm the object's interstellar origins and know more about its composition.
