Maybe in physical meaning. I am expecting also this comet to psikologically influence the mainkaind. I am referring to Nibiru myth as example.
I am speculating now, but if galactic alignment of our solar system is true, I have my doubts about accuracy of trajectory calculation.
If it resembles a pair of flutes, it is a portent for the art of music; in the private parts of the constellations it portends immorality; in relation to certain fixed stars it portends men of genius and a revival of learning; in the head of the northern or the southern serpent [i.e. Draco and Serpens] it brings poisonings.

I think it is going to be a great time to have one's eyes on the sky! I am trying to save up the cash myself to assemble a 8" Schmidt-Cassegrain telescope to really enjoy some of these events. As an aside, has anyone had any success in setting up a telescope up like this tied to an Android Tablet and use a CCD?
The Afrho calculation we performed on this dataset, (..), provided rather puzzling results:
- In short, we found a significant variation of the Afrho amount, according to the dimension of the measurement window (something pretty different from the steady state coma model).
The Afρ is simply the product between the albedo "A" (the reflectivity of grains), the filling factor "f" and "ρ" (the Greek letter "rho") that is the radius of the coma (usually in km) under investigation.
The filling factor “f”, is a quantity related to the optical density of the coma, and strictly speaking, is how much the total cross section of grains fills the field of view. It is the ratio between the total area filled by dust in the considered field of view and the area of the field of view itself.
A relevant property of the Afρ quantity (and it was the reason it was adopted) is just to have a constant (or nearly constant) value over a wide range of distances from the nucleus (ρ). This means it is not affected (or very little affected) by instrumental effetcs, different image-scale and measuring window sizes used in photometry.
steep photometric variation along the coma's profile, with a significant increase of the afrho values close to the central condensation .
Afrho maximum value of 1365 +/- 200 cm, for a corresponding aperture of nearly 16,000 km in diameter at the comet distance. After this peak, the Afrho amount decreases, reaching a minimum of about 900 +/- 200cm for apertures of 50,000 to 60,000 km.

The link is not BS, but claiming that the comet will be half as bright as the Sun is BS. To be that bright, the comet would have to be around -25.8 in magnitude.
See my post above about the apparent magnitude scale.
A huge comet is rounding the sun, a comet twice the size of jupiter (from tip to end of tail -ed) (about 22 times the size of earth). Some have seen it at sunrise and sunset; otherwise, it is not visible because it is occluded by solar glare. Essentially, it is coming from behind the sun and was first observed by NASA less than two months ago.
