So the size of ISON is 3 miles in diameter. But the coma (comet's aura) is speculated(or measured?) to reach 50000km - 120000km in diameter? Is that an accurate assessment? Even if the coma is that big, since the coma is not solid but a burned off material as it approaches the sun, do you really think it will add much to the gravity of the solid part of the comet? Just like the air surrounding the solid part of the earth, does the air affects earth's gravity? If not, and if gravity is only effected by the solid part of the sky object, then fear of large gravity effect may be unnecessary. But if the coma is really that big, then when it comes to nearer than 5.8 AU, we all may witness a very large object in the sky. Now, the doom may not be caused by the comet's gravity or the burning coma, but most probably caused by the panic of the non thinking sheeples who might think the end is near after noticing a very big object in the sky, just like the stampede of panic people in a room where all are rushing toward one exit door. So the more probable doom from this ISON comet is the doom and chaos caused by panic morons. How about that? |

Comet ISON for DUMMIES! Quoting: More questions than answers! Okay, this is a thread for everyone who is Non-technical and Non-astronomical but wants to know all about ISON and what the potential is for disaster in plain simple English! Firstly, what is a comet? A Comet, according to the experts is just a ball of ice and dust that lurks far away in space in an orbit around the Sun, just like we orbit the sun! Depending on how far away it is it can take years or tens of thousands of years before it comes around our way and we see it in the sky. At a certain distance from the Sun a comet forms a tail. Some tails can be hundreds of thousands of miles in length and are made up of dust and gasses from the main body or nucleus! When a Comet gets closer to the Sun it gets brighter because it "burns off" more of it's ice and gas at a faster rate, this produces something called a coma around it giving us that distinctive white ball ahead of the tail. A comets tail by the way, always points away from the Sun. When a comet reaches its closest approach to the Sun it's called perihelion which is just a clever term for closest approach! Not all comets survive perihelion because the Suns gravity can pull them apart, if this happens and any pieces survive they remain on the same course as the original comet. Okay! Sounds straight forward enough, so what's the problem with ISON, if anything? Well, there are many rumors and scare stories surrounding ISON. Some are just plain silly, but others might have some credence?! When ISON was first detected last September it was hailed by NASA as a "Once in a Civilisations lifetime" event. Some accolade for something only just recently discovered! So what was NASA comparing it too? Why did they say this? Why do they still says this when it's now supposed to be a dud - [link to solarsystem.nasa.gov] It just doesn't seem to fit somehow, does it?! So what DO we know about ISON for sure? Well, if we've been told the truth we know it's size was around 3 miles in diameter when first detected and it was at a distance of 5.8AU or 539,400,000 Miles. (AU is a clever abbreviated term for the distance from here to the Sun, known as an astronomical unit or 93 Million miles to you and I) So, here we have a very small object Millions of Miles away moving quite slowly and yet even then it was hailed as something very special, so special that NASA gathered together a team of over 200 people just to analyze it and then to forward that information on eventually to you and I, or so I thought! So, as you Americans like to say, what have we got so far for our buck from NASA Well, so far not very much. One image was released by NASA in January, but that's it. They've also managed to loose a probe sent to investigate and image ISON. It was named aptly enough "Deep Impact" - I hope it was insured?! Moving on, there have been others who claim that the coma, remember that's the bit that gets bigger as it gets nearer the Sun, is anywhere between 50,000 and 120,000km in diameter, that's the size of Saturn by the way! Now I've been trying to verify this information for weeks, but no matter how hard I try I just can't seem to find out the truth off the matter. Yes, we can get information from the internet or from NASA, but would you, or could you trust it? Let's just for one minute hypothesize! If ISON was around 50,000Km in diameter, or at least the size of Neptune what effects would or should it have on the Earth and to the other planets as it passes by? Large objects have large mass. The gas giants like Jupiter and Saturn have large mass and hence a lot of GRAVITY! Now I don't know if you remember school days and someone said if you could find a bowl of water big enough you could put Saturn in it and it would float?! Well, ISON is pretty much the same I reckon, it's mainly gasses and either its coma or nucleus could be as big as Saturn. If it is, and remember this is purely hypothetical, then logically it should have massive GRAVITY?! So, if we have massive GRAVITY then something must happen to the other planets as it passes them by, but more importantly what effect would it have on our Sun?!! We know the Sun drives our weather. We know the Sun recharges our atmosphere and feeds the Earth with light and warmth, but it can also turn very nasty if you perturb it! Have you ever heard of the term Barrycentre? No! Well imagine a seesaw with the Sun on one side and the planets on the other, they balance! Now, introduce another very large object with large mass and gravity on the side of the planets. Whoops! The balance tilts, and this is what would happen if you upset the Suns balance or Barrycentre by introducing such a large massive object into orbit around it. The Sun WOULD REACT WITH MASSIVE FLARING that would be unprecedented in our history! So, when will we know for sure just how big this Comet really is and if there's any real danger that we should worry about? Well, on the 1st of October the comet passes close to the planet Mars at around 7 Million miles distance, close enough for something to happen electrically if ISON is ANYWHERE near this size that I have hypothesized here. The electrical discharge between them wouldn't go unnoticed, believe me! If there truly isn't anything to worry about NASA will take full advantage of the flyby to use the probes already orbiting Mars to image the comet from the Martian perspective but the question is, will they? Anyone like to place a bet here? So, if nothing happens then that's it, right? Well, maybe not! Remember we talked about perihelion? Well if this chap is just a comet and it survives its journey around the Sun, it then heads back out again whence it came but worryingly as it does so it pass right over our heads! The problem here is, what's in its tail? They say that comets have brought plagues and pestilence in our distant past, but many dismiss this as pure conjecture! Well, maybe there right but then again what if they're wrong as this article from just a few days ago seems to suggest - [link to www.independent.co.uk] - So, comets could be transporting microbes to the Earth and we're just about to pass directly UNDERNEATH one...Brilliant! So, there you have it pretty much. I'm sure there's more but I think that about covers the basics. As I mentioned in the title, you should keep your eyes and ears open and use your own brain to assimilate the truth. If you need to be taken by the hand and led then this article is probably not for you and you should refer to others who may lead you unknowingly into the dark! Good luck to you all, no matter who you are and what happens next! ![]() ![]() just search the old comet elenin threads, you'll soon get the idea. |

Just to remind everyone that during its closest approach to the Earth comet ISON is supposed to be as bright, if not brighter than the FULL MOON NASA's words originally, not mine! Now just to put this into context, if you go outside you may be lucky to see Venus which is very bright but not as bright as ISON was/is predicted to be. Now ISON's core or nucleus is supposedly just 3 miles in diameter, okay! When it's supposed to be at it brightest ISON will be 39 Million Miles from the Earth, so that's a rock, 3 miles across will appear BRIGHTER than VENUS, which is around the same size as the Earth! At the time of closest approach both ISON and VENUS will be around the same distance from the Earth, therefore in order for ISON to be brighter than VENUS one would logically assume it would need to be the same size or slightly bigger! So, depending on how big it is forecast to be in our skies, and I don't know that for sure, it will need to be at least 12,000km in diameter, either the nucleus or the coma just to appear to be the same size as VENUS. ![]() Last Edited by More questions than answers! on 09/24/2013 04:17 PM Observe everything, trust no one and always follow the money!

Yes I understand this point, but what about my question! Quoting: More questions than answers! What gives Saturn its gravity if it consists mainly of gasses? And I replied to your other points separately, sorry! ![]() Gases can be compressed to give a higher density. And the huge amount of gas associated with Saturn creates a large gravity filed which causes the compression. So, what your saying, I think is that because Saturn has compressed gasses of huge density surrounding it, this is what creates its gravity? Gravity is caused by mass. The density of the gases which make up Saturn is large because the mass of those gases was large enough to compress them down to the size of Saturn. The density of the gases in ISON's coma is really small compared to Saturn. |
