A Ukrainian astronomer may have discovered a planetoid at the end of August that comes from a different planetary system, various international media write. It would only be the second rock from outside our solar system that enters the environment.
The new celestial body was initially named gb00234 and is located around 540 million kilometers from the earth. The initials 'gb' stood for astronomer Gennady Borisov, who signaled the fast-moving spot of light.
In recent weeks, however, the asteroid has been frequently photographed, allowing scientists to predict the orbit of the comet somewhat. The name has since been changed to C / 2019 Q4.
At the end of the year, enthusiasts can observe a 'normal' telescope C / 2019 Q4, after which the asteroid will fly out of the solar system at tens of kilometers per hour.
Second asteroid "from outside" that appears in our solar system
In 2017, astronomers in Hawaii discovered 'Oumuamua. That cigar-shaped comet was the first signaled asteroid that appeared in our solar system and would have taken 300,000 years to make the crossing from star Vega.
However, astronomers could learn "too little" from "Oumuamua," because the rock almost left the solar system when it was discovered. The new "cosmic invader" will be on display for almost six months.
Scientists do not exclude that more asteroids from outside our solar system fly by, but estimate that the majority are too small and too vague to see.
