Moons_Filmed_Around_Unknown_Sphere

Nope.
Moons Filmed Around Jupiter.
He's only about 400 years behind Galileo. And I bet Galileo didn't get in a flap about an 'unknown sphere'.
Such is progress.

By that I mean why come here instantly, rather than attempt to get to the root of the claims yourself first? Because you'll become a far more useful person, if that's the right choice of word, if you can think critically for yourself rather than rely on others.

Ask questions, sure. Ask questions that are easily answered through Google, for example, and it begins to tire. Help us out by helping yourself out.

You know this stuff is crap. Stop looking for it. Because what you are doing is dredging up the same old stuff we have talked about here endlessly, and asking us to debunk it again.

Just because there's a new video, doesn't make the claim new.

nope i was not it was a guy who have linked it in the elenin group im in

Elenin group? What are you doing in a "Elenin Group"? Scaring yourself?

The paper claims (on page 37) that Comet Elenin "has massive UFO Fleet following in formation in its tail

One to the things that whenever they show such a photo of Elenin and so called UFO is that they never show 2-3 images in a row spread over a few hours to show that it moves and not some background star or noise. When I looked at the images I grabbed, I could only detect Elenin when I blinked the images. To check what moved and what not.

The newfound planets are located at an average approximate distance of 10,000 to 20,000 light-years from Earth.

The second video is clearly about the sorts of disasters we experience here on Earth. They recommend reasonable, common-sense type stuff like have a week's worth of food, have a half tank of gas in your car, and seek an inside room in your house for safety (all done by memory, they may have worded it differently.) None of these things will protect NASA employees from doomsayer claims, so the NASA video cannot possibly be a response to 2012.

Capella to the northeast at apparent magnitude 0.6.

I guess those are the most likely suspects in the general vicinity of north. You could see Jupiter off to the east around that time, apparent magnitude -2.32 (very bright).
