Actually it sounds like Ursa Major.

That seems to be a galaxy and is not going to pass by between us and our sun/moon?

I read Elenin has a big tail, maybe that tail will darken our skies?

Ursa Major is a constellation. Elenin is not going to pass anywhere near our moon, let alone between us and the moon. Its orbit will not cause it to pass in front of the sun from our perspective either.

Yeah, SO WHAT. who cares. It will be so far away, i will need a telescope to see it. Another HOAX people. Just go away now , go away. Not even close for any impact.

Determine the influence of gravitational perturbations of a comet to an asteroid, using ground-based optical observations, unfortunately not succeed.

It specifically says that ground based observations would not be able to detect any such perturbation. This is because the comet's mass is too low to noticeably affect the asteroid. Even its tail had no effect. I confirmed this myself using a series of images I collected during time purchased on a remotely operated civilian telescope in the Canary Islands.

Elenin's position was predicted to be 10h 27m 32.27s, +08d 09' 03.5". According to astrometry, it was detected at 10h 27m 32s, +08d 09' 04", well within the 2.15 arcsecond per pixel resolution of the image. Asteroid 1999 RQ176 was predicted to be at 10h 28m 35.60s, +08d 05' 23.1". According to the same astrometry, it was actually detected at 10h 28m 36s, +08d 05' 23", again right on the money and within the resolution of the image.

I think C/2010 X1 is the cover for this brown dwarf.

We will see on this date wether or not we see a comet or a binary star system...

It's not a brown dwarf. A brown dwarf at Elenin's distance would be naked eye magnitude based on reflected sunlight alone. Instead, even my infrared sensitive camera can barely see it through my telescope. It would also severely perturb the orbits of not just nearby asteroids but the other planets as well.

A new site dealing with all FICTITIOUS aspects of Elenin. It is NOT a comet. If it were, it'd be the slowest comet on record. At the moment, this object is moving at 60,000 mph, the same as the Earth. But follow the JPL data base by all means and you'll see how its speed shoots up in late Summer.
A lot of trouble after that.

It appears that TPTB have already posted a warning in a recent Britney Spears "Till the World Ends" Music Video. I have taken a screenshot straight from the video.



Looks pretty interesting...

Hey guys last night I saw this movie on Syfy this movie it's called polar storm. It's about comet that distributes earth's magnetic field, stirs up electrical storms and flip the earth magnetic poles.

What sticks out to he about this movie is that it's focus on a comet bringing earth changes, these earth changes effect electronic equipment. These electric storms kill people and the atmosphere gets weak letting cosmic radiation into the earth(kills more people). In the movie the comet is responsible for earthquakes and changes(the comet dist rub the relationship between the earth and the sun by 10 degrees).Which fits well with the 3 days of darkness roman catholic prophesy with only blessed candles working and demons roam the earth. The only key missing from the movie is the 3 days of total darkness for the catholic prophesy, as for the general Elenin prediction it matches up.

I saw this only once movie back in 2009, so I might be rusty on the plot of the film.

Check it out, i think it's worth a look.

Completely and totally wrong. Not even close, in fact. Elenin's current sun-relative velocity is 28.95 km/sec. Comet C/1993 Y1 McNaught-Russell, for comparison, has a current sun-relative velocity of 6.53 km/sec. Comparing apples to apples, Elenin's current sun-relative distance is about 2.13 AUs. When comet C/1993 Y1 McNaught-Russell was 2.13 AUs from the sun in 1993, its sun-relative velocity was only 28.03 km/sec, almost a full km/sec slower than Elenin.

That's how orbits work. The farther away you are the sun, the slower you go. As you get closer to the sun, you speed up. There is absolutely nothing unusual about Elenin's orbit or speed.

Take, for instance, Halley's Comet. It has an orbital period of about 75.3 years (27,509 days). It travels out to an aphelion (farthest distance from the sun) of 35.1 AU (5,250,889,800). During one full orbit, it travels roughly twice that distance. So it's average velocity over the course of one orbit is a mere 4.4 km/second (9,842 mph).

In fact, Halley goes much slower than that when its far away from the sun for most of it orbit. It then speeds up to be much faster as it gets closer to the sun. But it all averages out to be a measly 9.842 mph.

Hi people! Just thought about posting an update, as I've been following Mr. Elenin's website, as well as his facebook page. I hope people won't start bombarding him with friend requests. For now, he's been answering some questions..still not answering others. Doomsayers have been bothering him, so please, don't be another one, as you will be deleted/blocked. Here's the post I made with some questions.

Ok.... If he saw and discovered the comet 5 months ago, and it is a lot closer now, why can it not be seen now? Weird, if you ask me.

reply to post by thorazineshuffle


Maybe knowing some more about astronomy will answer that. Ask some of the experts on this forum, as I have no time. The object won't be seen again after the beginning of July I think, that's how the universe works, celestial bodies move and stay in front of others.

It is not a very large comet. It was spotted further away from the Sun than most comets, which is why it is of interest to astronomers. The comet's nucleus is a loosely packed chunk of rocky material and frozen gases no more than a few kilometers across. As it nears the Sun, the gases begin to sublimate... let's call that "boil in the vacuum of space" and form a cloud called the "coma." This coma is what grows as the comet approaches the Sun. Although the coma can be thousands of kilometers across, the gas is so thin as to be a nearly perfect vacuum. The solar wind sweeps this gas into a tail that faces away from the Sun at all times. (There is also usually a secondary tail caused by the pressure of sunlight itself.) Because it was spotted so far out, astronomers are happy to observe this whole process from an earlier point. Other than that, there is not much exceptional about this comet beyond it being the first discovered by a Russian. Dozens of comets are discovered each year, and very few of them ever become visible to the naked eye.

Not be seen by the naked eye? It's still about 275,000,000 km away. *WAY* too far away to see with the naked eye. It can be seen with telescopes, though.

Thanks for the explanation! I should have phrased my question a little differently. What I should of asked was, in the copy of text from Elenin's facebook page, he stated that a telescope could not locate the comet now. Why would you not, as it is much closer now than it was 5 the ago when he discovered it.

I misphrased my question, sorry. See my response above. Thanks!
