Newfound Comet Likely An'Interstellar Visitor Say Scientists

Scientists Discover Possible Interstellar Visitor

The comet is named in part after the person who discovered it, amateur astronomer Gennady Borisov, who first spotted it on August 30th from the Crimean Astrophysical Observatory.

In January, researchers published a study that suggested Oumuaua was not one-of-a-kind and there may be many other interstellar objects floating around the Milky Way galaxy. There has also been speculation in the scientific community that Earth was hit by an interstellar object in 2014, added. Its hyperbolic orbit indicated it had arrived from afar and wouldn't be coming back. "The high velocity indicates not only that the object likely originated from outside our solar system, but also that it will leave and head back to interstellar space". An unknown object has entered the solar system, and it is likely to have come from an alien world.

"So the question we'll be wanting to answer is: what's the composition of the coma - the fuzzy bit around the comet core". That's always an issue with comets, so you've got that unpredictability, combined with the fact that it is interstellar. And this is the first interstellar comet we've seen, ' astronomy-software developer Bill Gray, told Forbes.

They found that the object is well outside the ecliptic (the plane of the Earth's orbit around the Sun) and is headed for the inner solar system at an angle of 40° and a present speed of 93,000 miles per hour (15,000 km/h).

The mysterious cigar-shaped projectile, formally named object 1I/2017 U1, resembles both a comet and an asteroid, however, it doesn't conform to numerous other defining features usually associated with these objects, including its direction of spin and lack of a tail. With Comet C/2019 Q4 (Borisov), though, the circumstances are different, since it was discovered on its approach to our solar system and hasn't yet reached perihelion - its closest pass by the Sun. The asteroid, Oumuamua, was leaving and this left them with very little time to study it. The past week of observations, including this image taken by the Canada-France-Hawaii Telescope on Hawaii's Big Island, have increased astronomers confidence that the comet started life in another solar system.

Researchers had just weeks to collect as much data as possible before the odd visitor travelled beyond the reach of Earth's telescopes. Initially dubbed gb00234, the International Astronomical Union (IAU) has confirmed the object to be Comet C/2019 Q4 (Borisov).

Astronomers will now be able to compare their findings on Oumuamua with the most recent specimen. That's the plane in which the Earth and planets orbit the Sun.

Astronomers may have spotted the second object ever to visit our solar system from another star system.

However, it displays none of the classic behaviour expected of comets, such as a dusty, water-ice particle tail.

That aspect ratio is greater than that of any asteroid or asteroid observed in our solar system to date. But C/2019 is still making its way into the solar system and should stick around for at least six months. The closest the object will come to Earth is roughly the same distance, 190 million mi.

Alien hunters at SETI - the Search for Extra-terrestrial Intelligence based at Berkeley University, California said there was a possibility the rock was "an alien artefact".
