Nasa is a running joke at the European space agency.
I assume this means you are employed by the ESA. Please share some of these "in jokes" with us....
In the process of these gases coming out, it introduces a rocket-like thrust on the comet itself, and we have to try and model that in order to predict where these things will be. Some comets have fits and starts and their outgassing is not at all uniform or regular, and their nuclei (spin-axis) are chaotically moving with time, which makes it very difficult to model their motions.
Encke's short period combined with its trajectory inside the orbit of Mercury means it may have been blasted by CMEs more often than any other comet routinely observed by astronomers. Could this have some effect on the comet's nature and evolution? "We don't yet know."
One of Bernays' favorite techniques for manipulating public opinion was the indirect use of "third party authorities" to plead his clients' causes. "If you can influence the leaders, either with or without their conscious cooperation, you automatically influence the group which they sway", he said. In order to promote sales of bacon, for example, he conducted a survey of physicians and reported their recommendation that people eat heavy breakfasts. He sent the results of the survey to 5,000 physicians, along with publicity touting bacon and eggs as a heavy breakfast.
Bernays' public relations efforts helped to popularize Freud's theories in the United States. Bernays also pioneered the PR industry's use of psychology and other social sciences to design its public persuasion campaigns:
"If we understand the mechanism and motives of the group mind, is it not possible to control and regiment the masses according to our will without their knowing about it? The recent practice of propaganda has proved that it is possible, at least up to a certain point and within certain limits."
Bernays helped the Aluminum Company of America (Alcoa) and other special interest groups to convince the American public that water fluoridation was safe and beneficial to human health. This was achieved by using the American Dental Association in a highly successful media campaign
Bernays' most extreme political propaganda activities were said to be conducted on behalf of the multinational corporation United Fruit Company (today's Chiquita Brands International) and the U.S. government to facilitate the successful overthrow (see Operation PBSUCCESS) of the democratically elected president of Guatemala, Jacobo Arbenz Guzman. Bernays' propaganda (documented in the BBC documentary, The Century of the Self), branding Arbenz as communist, was published in major U.S. media. According to a book review by John Stauber and Sheldon Rampton of Larry Tye's biography, "The Father of Spin: Edward L. Bernays & The Birth of PR",
"the term 'banana republic' actually originated in reference to United Fruit's domination of corrupt governments in Guatemala and other Central American countries. The company brutally exploited virtual slave labor in order to produce cheap bananas for the lucrative U.S. market."
Chilean poet Pablo Neruda would later denounce the dominance of foreign-owned banana producers in the politics of several Latin American countries in a poem titled "La United Fruit Co."

My only question is, if it is, as NASA states a fairly insignificant ball of ice and dust, then why is such a big deal being made about it? You wouldn't go through so much trouble if the truth was insignificant. Sort of like the presidents birth certificate.

Can anyone predict how much thrust Elenin will gain as it passes the sun?
And have every amateur astronomer accounted for this thrust?
