Comet Elenin is not a danger to the Earth

Comet C/2010 X1 (Elenin) is a comet discovered by Russian astronomer Leonid Elenin on December 10, 2010. Elenin was using a robotic observatory near Mayhill, New Mexico.

Mr. Elenin is an amateur astronomer from Lubertsy City, Russia, near Moscow. He is a graduate of the Moscow Aviation Institute, works as a researcher at the Keldysh Institute of Applied Mathematics (Russian Academy of Sciences), is married, and is bilingual (Russian and English). He volunteers with the International Astronomical Search Collaboration, and runs a website at http://SpaceObs.org. He has had a passion for astronomy since childhood, and studies minor Solar System objects and variable stars. He has discovered more than 10 variable stars and numerous asteroids, and now, a comet.

On December 11th, 2010, Leonid Elenin posted news on his site of a “new and interesting object” discovered during a “routine survey of the sky on Dec. 10, 2010”. The discovery was made at the independent Russian remote observatory ISON-NM, which is located near Mayhill, New Mexico. The observatory is operated under the Russian project ISON (International Scientific Optical Network). His observations were confirmed by Aleksei Sergeyev and Artyom Novichonok at Madinak Observatory in the Ukrane.

Initially the comet was thought to be a short period comet, with aphelion near the orbit of Jupiter, and a perihelion inside the orbit of Earth. However, over a week after its discovery, the Minor Planets Center at Harvard published the orbital elements, revealing that the perihelion would be near Mercury! It was still unclear as to whether this was a rogue (a one time event) or a periodic comet. Further observations and calculations show that its period is on the order of 10,000 years, and that this is likely its first pass through the inner solar system. This leads to the prospect of a very bright comet in 2011. Leonid Elenin also estimates that the comet nucleus is 3-4 km in diameter.

According to the JPL Small Body Database C/2010 X1 is a Hyperbolic Comet, meaning that it will not return. However, Leonid Elenin has calculated that due to perturbations to the comet’s orbit from the gas giant planets, that the orbit of his comet will be modified to a long-period elliptical orbit, and that it will return in about 10,000 years.

Comet Elenin is in an orbit that is close to the plane of the ecliptic. It is currently just past opposition and about 3 times farther away from us than we are from the sun. Here is an illustration of the comet’s orbit as of April 5, 2011.

In August 2011, Elenin will become a naked-eye visible object, as it sweeps in closer to the sun than the Earth is.

By September 1st, 2011, Comet Elenin will approach the orbit of Mercury, and it will reach Perhelion on September 5th. In just a little over a month it will have traveled from the orbit of the Earth to the Orbit of Mercury. At this point it will be so close to the sun from our vantage point that it will be completely hidden. However, it will be visible on solar-observing spacecraft such as STEREO and SOHO.

On October 17th, 2011, Comet Elenin will make its closest approach to the earth. However, its distance to the Earth will still be huge, nearly a quarter of the distance between the earth and the sun.

Wild Claims.

Instead of being excited about the possibility of a naked-eye visible comet, some people are making some very strange and wild claims about the comet, or about Leonid Elenin. Some people are apparently questioning whether Leonid Elenin is even a real person, despite the fact that he is acknowledged as a contributor in various scholarly journal articles since 2009.

Elenin will not collide with Earth.

At its closest approach, Comet Elenin will be 34 million kilometers (21 million miles) away from the Earth. It will also be 4 million kilometers (2.4 million miles) above the orbit of the Earth. See this image showing that Elenin will be well above Earth’s orbit, and this image, showing it will be well ahead of the earth in it’s oribt and the videos below created by 2012hoax.org member obaeyens using the orbital simulator AstroGrav.

The Earth will not pass through Elenin’s tail.

A common misconception of comets is that the tail streams out behind the comet. Even if that were the case, the images and video above show that we would not pass through the tail. However, the tail of a comet does not stream out behind the comet’s path, but rather points away from the Sun. As such, the tail will never be in a position to cross the path of the Earth.

Even if the Earth were to pass through the tail of the comet, the only effect on the Earth would be a nice show of meteors. The Perseid meteor shower occurs every year between August 9 and 13 when the Earth passes through the orbit of Comet Swift-Tuttle. Comet Halley is the source of the Orionid shower in October.

Leonid Elenin is a real person.

Yes, it has been claimed that “Leonid Elenin” does not, in fact, exist, but that instead his name is a ‘coded message’. The poster finishes off a list of what they see as ‘hints’ in the circumstances with the statement:

You know the way TPTB operate. Everything is scripted well in advance and they use Hollywood to drop clues.

Or, it could be that the poster watches too many fictional movies and thinks that they are ‘coded messages’ from “The Powers That Be”.

Does Leonid Elenin even exist? http://www.abovetopsecret.com/forum/thread675535/pg1

Comet Elenin a “smokescreen” for Nibiru: http://humansarefree.com/2011/02/elenin-comet-smokescreen-for-nibiru.html

Don Yeomans on C/2010 X1

Don Yeomans has weighed in on the comet, saying:

“So you’ve got a modest-sized icy dirtball that is getting no closer than 35 million kilometers,” said Yeomans. “It will have an immeasurably miniscule influence on our planet. By comparison, my subcompact automobile exerts a greater influence on the ocean’s tides than comet Elenin ever will.”

NASA’s David Morrison on Comet Elenin claims

“The comet never comes close to the Earth, but it is expected to be visible in binoculars during August and October. Part of the Internet chatter concerns its size. Comets are exceedingly small and enveloped in a tenuous cloud of gas and dust, so the only way to be sure of their actual dimensions is to visit with a spacecraft. This means its mass is less than one billionth the mass of the Earth. Needless to say, we will not be aware of the tiny gravitational pull from Elenin.”

This is a quote from a David’s answer to a question on the “Ask an astrobiologist” page. He has received lots of questions about Elenin as well.

    By any information that has been given to us through reputable sources(NASA, mainstream media) your 100% right. Elenin is of absolutely no danger if its the size they claim, takes the route they claim. Although I did read a NASA post on it saying that it was unlikely to hit earth but that they never can be sure because comets are known to change trajectory, so saying it’s impossible would be negligent. Thats coming right from NASA so…I mean I understand you wanting to dumb down the doomsday theory with saying ITS OF NO THREAT because they’re filling the world with fear lol including me. To be honest i’m in between, but your claim is as unreputable as the ones claiming it WILL FOR SURE in fact hit earth. They just found it, it’s never actually passed earth in OUR time so truly a trajectory is a guesstimate in the first place. On the same end lies hundreds of comets wizzing by per year that don’t destruct the world. Destruction of the world HAS happened many times, it’s moronic to say it couldn’t happen, unlikely…For real, I don’t want the world to end I’m 23 just starting my life. Weeding through the facts for the last nine months, things appear to be changing on earth. But who knows this change could be a thousand year process that we’ll never notice MAJOR change in our life. I dunno. I’ve resorted to a telescope, facts, watching the sky. If it’s big, we’ll see it in two months or less. But making outrageous claims of WILL or WILL NOT are all in the same. Keep ya eyes to the sky, it’ll tell us all what we’re wanting to know…but nice research I won’t say you’re radical with the idea that it could in fact be of no threat! My hopes are on your side…but the brain has to ponder what’s given.

    oh right one thing I forgot to mention, read into NASA and govt. procedure on informing public of an event that IS a threat to earth. Stated in their own words…they would most likely give 48 hrs. notice to avoid mass panic. Their words…not mine. Even though to ninety percent of the population thats a completely obvious statement..I mean who doesn’t know that the media and the govt. lie lol.

    We can say for certain it will not hit. Data is being updated all the time and nothing has changed. At its closest it will be 34 million kilometers (21 million miles) from Earth. This may slighlty change one way or another as it gets closer but no way will it change by millions of miles. There is nothing it can now encounter on its way to the inner solar system that will have a drastic gravitational affect on its orbit. From what we can see this comet is getting the “Doomsday” treatment from fear mongers simply because of its name and it’s a very recent discovery. Other comets were not discovered until they were basically on our doorstep. Its happend, and will continue to happen and when it does there will always be people screaming “the end is nigh”. Remember Hale-bopp? There is another comet, 45P/Honda-Mrkos-Pajdušáková, that will pass significantly closer to Earth than Elenin (0.0601 AU – 8,990,000 km – 5,590,000 mi) in August this year and we have far less fear mongers screaming about that! Also about the NASA 45 minute warning thing. First, do you have a link? Second, you wouldn’t need NASA to blow the lid on something like that. With the thousands of astronomers out there who have nothing to do with NASA who also track these things, they could not and would not keep it quiet.

    Hi, I have one question that I want answered to be 100% sure that NASA isn’t hiding anything from us. If you look at the Virgo constellation in google sky (viewing with infra-red) pan slightly left and down and you will see that something has been censored. What is this? Many people have been saying it’s Nibiru. I don’t say I believe them, but it does raise an eyebrow for why is NASA censoring this out for if it’s just a measly little comet that poses no threat to us? If someone could answer that with fact and not their opinion than that would put my mind at ease. Please reference your answers.

    @Concerned Australian

    That particular area in Google Sky has been talked about for a number of years. Nothing is being hidden here and it’s not the only “black box” found in these applications.

    The black box represents missing or corrupt data that could not be ‘stitched’ with the surrounding data. There are several in both the SDSS, the DSS2 and the IRAS data sets.

    The Virgo area is “target rich” for amateur astronomers who like deep sky objects. We don’t generally rely on MSWWT or WikiSky or GoogleSky (although we like to use them from time to time).

    If you’re very concerned you can get an account with one of the many remote telescope companies (like slooh.com, for example) and image that area yourself. Or better yet invest in your own telescope.

    Another way to look at it is this: Fire up wikisky or WWT or Google Sky. Select DSS2 as the source. Find spica. Now find the blue blob to the northwest of spica. That’s a glitch in the optical data. Now switch to SDSS data. Spica’s gone, because the SDSS data doesn’t cover it! Now switch to IRAS. There’s a black square to the SE of spica. That’s a glitch in the infrared data.

    Nothing is being hidden.

    There are plenty of sources out there that go into more detail about this, for a start we recommend you read the article 2012Hoax.org wrote which can be found by clicking the link below.
