Tailless comet

Comets are asteroids with higher electrical potential difference?

Evidence with K2 comet having a relatively supermassive coma but still freezing cold as further than Saturn from the Suns heat. Also, no cometary tail.

Will the active asteroid (comet) produce a cometary tail as its potential difference increases as it gets closer to our plasma star?

Will comet C/2017 K2 coma increase or decrease in diameter as it changes from a tailless comet to one with a million miles and longer plasma tail?

tailless comet electric universe theoryA team of astronomers led by UCLA professor David Jewitt has identified a 'special comet' 1.5 billion miles from the sun. No other comet heading toward our sun has ever been seen at such a great distance.

... C/2017 K2 (PANSTARRS), or K2 for short, is currently beyond Saturn's orbit, and it has been traveling for millions of years from its home in the frigid outer reaches of the solar system, where the temperature is approximately 440 degrees below zero Fahrenheit.

... K2 has begun to develop an 80,000-mile-wide fuzzy cloud of dust, called a coma, that contains a tiny, solid nucleus of frozen gas and dust. The new observations represent the earliest signs of activity ever seen from a comet entering our solar system's planetary zone for the first time, as K2 is.

... Because K2 is so far from the sun and so cold, water ice there is frozen like a rock, and we know for sure that the activity - all of the fuzzy stuff making it look like a comet - is not produced by the evaporation of water ice, as it is in other comets

... determine the width of the coma and helped Jewitt estimate the size of the nucleus—less than 12 miles across—although the coma's diameter is as wide as 10 times the diameter of the Earth.

The K2 tailless comet still has a tale to tell

One interesting aspect of Hubble's K2 images was the absence of a "tail"—a signature feature of other comets ... "It should become more and more active as it nears the sun and presumably will form a tail," Jewitt said. The comet will make its closest approach to the sun in 2022, when it will pass just beyond Mars' orbit.
