When an astronomer from the Crimea Astrophysical Observatory, Gennady Borisov, entered an unusual interstellar object in our solar system on August 30, 2019, the scientific world was given the opportunity to significantly expand their knowledge of comets – extremely useful objects for the mining of the future , According to an article published on science101.com, almost immediately after the comet's discovery, the NASA messaging system found that the object's orbit was very unusual compared to its predecessor, the asteroid Oumuamua. What is the uniqueness of Comet C / 2019 Q4 in and is it dangerous to humans?
A comet from another star system broke into the solar system
We have already written that the mysterious asteroid Oumuamua flew into the solar system about three years ago, which has helped scientists from all over the world understand the mechanism for the movement of interstellar objects. Unlike Oumuamua, the discovered Comet C / 2019 Q4 will be a much more traceable object over a longer period of time, which can provide even more useful data on the structure of the universe for modern science.
As you know, all objects in our solar system are tied to the Sun's orbit – a heavy center that does not allow its planets, including our Earth, to fly far into the open. Both Oumuamua and the second interstellar object, named after the first astronomer to discover its presence in close proximity to us, were not in normal orbits, leading scientists to the idea that the only place that had the origin of both Objects might explain, deep space should be.

Since the discovery of comet C / 2019 Q4 in summer 2019, the object has been studied by three different groups of astronomers who confirmed that the comet came from another galaxy. According to their calculations, the interstellar wanderer came closest to Earth on December 29, when it was between the orbits of Jupiter and Mars. It is also known that the comet has a diameter of several kilometers, releases dust and gas and surrounds itself with a bright halo.

Astronomers are confident that a unique comet can be observed from Earth all year round, about 8 months longer than the Oumuamua asteroid, which offers professionals much more opportunities to work. Since Oumuamua was rather unusual in its composition and an extremely inaccessible observation object, it was difficult to decipher the exact size and origin of the object without a doubt. In contrast, comet C / 2019 Q4 shows all the signs of a planetary enzymatic past and is inherently the remaining planetary building block far beyond our solar system. To prove this fascinating hypothesis, astronomers still have a lot of time to study Borisov's comet, which, as is so often the case, will cause us even more riddles in the near future. In any case, the discovery of a comet means that by 2020 we will be able to re-examine interstellar objects and move them around in space.
