A comet that may coming from outside our solar system

A comet that may coming from outside our solar system has been discovered. If confirmed, this would be the second interstellar object ever identified, with the first one being 'Oumuamua, found in 2017.

The new comet, dubbed C/2019 Q4 (Borisov), was discovered by the Ukrainian amateur astronomer Gennady Borisov in Crimea on August 30th, 2019. The new object, which sports a fuzzy coma in images, would also be the first definitive interstellar comet. Oumuamua looked like an asteroid and behaved a little like a comet.
The new comet is still inbound toward the Sun, but it will remain farther than the orbit of Mars and will approach no closer to Earth than about 300 million kilometers.
The comet's current velocity is high, about 150,000 kph, which is well above the typical velocities of objects orbiting the Sun at that distance. 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.
On Oct. 26, it will pass through the ecliptic plane from above at roughly a 40 degree angle.
C/2019 Q4 was established as being cometary due to its fuzzy appearance, which indicates that the object has a central icy body that is producing a surrounding cloud of dust and particles as it approaches the Sun and heats up.
Since asteroids and comets are believed to be leftover material from the formation of a system, knowing what this comet is composed of will allow astronomers to learn a great deal about where it came from. This is one of the greatest benefits of interstellar objects, in that they allow us to learn more about distant star systems without actually having to send robotic spacecraft there.
