Astronomers have observed the first comet from outside the solar system

“The object is moving very fast and the trajectory is such that we can confidently say that this object is coming out of the solar system and will not come back”.

Astronomers have recently discovered a new object (an asteroid or comet) that they believe could be a visitor coming from outside the solar system. The A / 2017 U1, passed near the Sun on October 18 and its trajectory leads scientists to believe that it came from afar. If in fact you confirm that you are an interstellar visitor, this will be the first to be observed by astronomers in our neighborhood.

The A / 2017 U1 is less than 400 meters in diameter and moves at high speed, according to the US Space Agency (NASA). It was detected on October 19 by a telescope at the University of Hawaii.

Rob Weryk was the first to identify the object, and soon astonished his orbit, which did not strike with the possibility of being a comet or asteroid of the solar system, in this way, contacted colleague Marco Micheli, who reached the same conclusion using for it images of a telescope of the European Space Agency (ESA) in Tenerife, Canary Islands.

So, and joining all the data, the conclusion seems to be that the A / 2017 U1 came from outside the solar system. “This is the most extreme orbit I have ever seen. It is moving very fast and the trajectory is such that we can confidently say that this object is coming out of the solar system and will not come back”, said Davide Farnocchia of the Center for the Study of the Near-Earth Objects of NASA.

The A / 2017 U1 came from the direction of the Lira constellation and is traveling at 25.5 km per second. It passed “close” to Earth (24 million kilometers) on 14 October.

“We’ve been waiting for this for decades”, said Paul Chodas of NASA’s Center for the Study of Near Earth.
