Comet C/2019 Q4 (Borisov) - Predictions, Comments?

Unread post by lmurarka » Fri Sep 13, 2019 1:31 pm

Quoted from

"INTERSTELLAR COMET: 'Oumuamua is not alone. Another interstellar visitor appears to be passing through the solar system--and this time it's definitely a comet. Ukrainian amateur astronomer Gennady Borisov discovered the object, now named C/2019 Q4 (Borisov), approaching from beyond the orbit of Mars on Aug. 30th.

Based on observations gathered since Borisov discovered the distant fuzzball, the comet seems to be following a hyperbolic orbit with an eccentricity greater than 3.5. This means the comet is unbound to the sun. Indeed, it is moving some 30.7 km/s (68,700 mph) too fast for the sun's gravity to hang onto it. Comet Borisov is a first time visitor to the inner solar system, and after this flyby it will return to deep space.

Comet Borisov will make its closest approach to the sun (2 AU) around Dec. 7th. Three weeks later, near the end of December, it will make its closest approach to Earth (also 2 AU). At the moment the comet is very dim, around magnitude +18. How bright it may become by December is anyone's guess. ... 289244.jpg

Above: Dim and distant, Comet Borisov was photographed in the constellation Cancer on Sept. 12th by Graziano Ventre using an 11-inch telescope."

So Comet 2I/Borisov is now passing through our solar system at a distance of about 300million km. This is an unusual opportunity to test electric comet hypotheses. What specific prediction do (Don Scott, make about the interaction of this interstellar object with the solar electrical environment? What kinds of materials are expected in the coma/tail? I would not be surprised if it was found that the core looks like one of our typical asteroids or active asteroids, perhaps bi-lobar (peanut shaped) and stony/dusty, rather than "dirty/icy"...
I'm kinda hoping to be surprised!
Truth extends beyond the border of self-limiting science. Free discourse among opposing viewpoints draws the open-minded away from the darkness of inevitable bias and nearer to the light of universal reality.
