We have visitors from outside our solar system, and the more information we collect, the more interesting things become.
Comet 2I / Borisov is the second “invader” that we observe its pathway, and from astronomers’ early discoveries, it appears to have characteristics such as comets across our solar system. It is also worth noting that 2I / Borisov has a red tint, which makes it more attractive.
Facts and Dates of Comet 2I / Borisov
Astronomers have confirmed the condition of Borisov’s comet as an interstellar object whose trajectory and velocity indicate to come from outside the known limits of our solar system.
Objects were observed moving at a speed of 110,000 miles per hour. This is faster than the man-made spacecraft that traveled across the boundaries of our solar system and is now officially an interstellar object. We are talking about the Voyager sensors released in 1977.
2I / Borisov is just the second example of an interstellar object coming from another solar system from us.The first is Oumuamua in 2017, a strange long, cigar-like hyperbolic asteroid.
While Oumuamua’s appearance was extremely bizarre. But the properties of 2I / Borisov are more comet-like as they are when 2I / Borisov is near, we expect it to increase its brightness from 17 to 15 at the nearest point, and expect it to happen next December 28.
To date, many 2I / Borisov spectra have been collected from the William Herschel Telescope in the Canary Islands, including the Gemini North Telescope in Mauna Kea, Hawaii. We especially Hale-Bopp in 1997.
While it is nothing more than a faint object at this time, many amateur astronomers hope they will be able to take a closer look at 2I / Borisov when it reaches the point closest to the Sun or more precisely. This is expected to happen around December 8.

With a 10-inch telescope under equivalent conditions, there is an opportunity to legally view 2I / Borisov.
Visibility depends on the DC value of the coma, that is, the degree of condensation.
A DC value of 0 indicates an object that is completely scattered and scattered without condensation at the core, while a DC value of 9 indicates that the object is so dense and dense that it forms the shape of a star.
Size is also an important factor in vision. Larger and longer objects are generally more difficult to recognize compared to smaller and denser ones.
As of this writing, 2I / Borisov looks small, dense and compact. If this continues throughout the visit, experienced comets’ trackers may be able to observe them with a 10-inch telescope.
Telescopes larger than 12 inches in dark and light-free conditions have a better chance of observing 2I / Borisov.
Regardless of which telescope is used, an important trick to keep in mind is to use a high magnification setting to focus on smaller objects while blurring the background at the same time.
Environment and breastfeeding (8 December)
Weather, as well as high altitude conditions, will play a role in determining whether observers will spot Borisov’s comet on Dec. 8, a cloudy sky often poses a challenge for comet watchers in the United States.
Borisov will be at its peak before dawn, especially in the southern sky. Usually it is five in the morning.
Comet 2I / Borissov is expected to be the brightest and brightest from early December to January 2020.
It’s a good idea to have comet watchers of the north search for the sky in early December, prior to the appearance of the solar moon around December 11, the moonless sky is expected to return in the day. This month’s 22nd bid makes that bidding good for observers, especially for observers in the South and beyond.They’ll most likely enjoy the opportunity to enjoy Borisov’s views throughout their stay.
The comet still maintains its appeal even after it has passed. In fact, the comet has been shrouded in mystery over time. They spark an unanswered interest and thirst for knowledge every time they appear. It is the same attraction that inspires comet watchers from all walks of life and in every location to find, question and wonder.
What makes C / 2019 Q4 different from almost all comets is the orbital deflection. Decentralization measures the amount of orbital deflection from a complete circle whose deflection is 0.The typical elliptical orbit of planets, asteroids, and comets has a deviation between 0 and 1, the parabola is equal to 1 and the deviation.
In the days of its discovery thereafter, it had been temporarily designated gb00234. Observers were cautious about the possibility of interstellar formation. The chances of finding it in the pre-detection photos are slim, as the comet was so close to the sun that it was cleared from a large survey. But it should remain visible for months before and after approaching the Earth in December, and further point measurements will tighten the orbital alignment and be a stronger case for the interstellar origin.
Meanwhile, the images show that the oncoming body suffers from a faint but different coma and the slightest hint of the tail – something Oumuamua lacks – and appears to have. wrong Astronomers have no doubt obtained a spectrum of new discoveries to determine which compounds may have escaped their surface.
Based on current observations, the C / 2019 Q4 power dissipation deviation is approximately 3.2 – a definite conclusion. Objects in hyperbolic orbit are not bound to the Sun. They tend to descend from outside the solar system and fly remotely for a short visit to our region before heading for an unknown part.
If this discovery persists, astronomers will have an unprecedented opportunity to study interstellar bodies in detail over a long period of time. Based on the comet’s current size (~ 18) and its distance from the sun (2.7 au), it appears to be quite large – perhaps 10 km or more wide depending on its surface reflection.
