Astronomy: Possibly discovered new interstellar comet

An amateur astronomer may have discovered the next interstellar visitor to our solar system – a comet tentatively named C / 2019 Q4 (Borisov). The International Astronomical Union's Minor Planet Center has compiled the data available to date, stating that "they suggest an interstellar origin."

He would have caught the eye of'Oumuamua, the first known interstellar object in transit in the fall of 2017. The possible interstellar comet has now been discovered by an astronomer named Gennady Borisov told the Minor Planet Center,

C / 2019 Q4 is relatively difficult to observe due to its position in the sky – near the sun – said the head of the Minor Planet Center explained to Gizmodo, However, the center has called more observations "desirable" – also to find out if it really originated outside the solar system.

The previous data on the trajectory of the object therefore does not only indicate a hyperbolic orbit on which C / 2019 Q4 will leave our home system. First of all, however, the object should be "observable for at least a year," as the Center explains. According to the analyzes, it is an active comet, so analyzes of the tail could allow a look at its composition.

The potential interstellar comet now evokes memories of 'Oumuamua, which was discovered at great speed in the Solar System in 2017. The celestial body, later classified as an asteroid, was also first thought to be a comet. Later it was said again, it is still a comet, but in the meantime there is talk of an interstellar object. Its full name is 1I / 2017 U1 ('Oumuamua). 'Oumuamua' is of Hawaiian origin and describes a messenger sent from the distant past to contact us.
