Worried About Comet Elenin? FAQs from Ian Musgrave. Astroblog was not the only site that was targeted, and thankfully, Ian’s web host agreed that the claim was without merit, and the posts are back online. Have your questions answered below. Will Comet Elenin Hit Earth?: No, its closest approach is 0. AU on Oct 1. 6, 2. Search the history of over 491 billion pages on the Internet. Yili Fang, Hailong Sun, Richong Zhang, Jinpeng Huai, Yongyi Mao, A model for aggregating contributions of synergistic crowdsourcing workflows. Year of the Comet (1992) AKA titles.

To put this in perspective, this is only a little closer than the closest approach of Venus to Earth, and roughly 1. Earth to the Moon. This distance is from the latest MPEC ephemeris which is based on over 1. Surely if Elenin Was Going to Hit the Earth NASA/the Government Would Hush it Up? The Australian Government, the UK Government? The Italian Government? The South African Government? Amateur astronomers world wide are following this comet and continually talking to each other. The have the programs to work out where the comet is going. If the comet was coming anywhere near us, the amateur community would be first to know, and there is no keeping them quite. Consider how wide spread the information is about Apophis, which is a real, if extremely marginal, hazard. Will it Cause Earthquakes, Abnormally High Tides or Other Disasters: No, Elenin is a mere 3- 5 kilometres across and has less than a billionth of the tidal force of the Moon at closest approach (as well as a negligible magnetic field). If the Moon can’t cause the poles to tip, cause massive tidal floods or earthquakes, Comet 2. X1 Elenin won’t. We’ve been closer to other comets before with no ill effect. But What About Mensur Omerbashich’s Paper that Says Elenin is Causing Earthquakes? It shows nothing of the sort, earthquakes are no more common during comet alignments than at any other time. But it’s bigger than Jupiter! No, that’s the coma , the thin haze of gas and dust that surrounds the comet nucleus. The nucleus of C/2. X1 Elenin is roughly 3- 4 Km in diameter and Elenin has a coma around 5. Jupiter). The average density of the coma is about the same as the density of the atmosphere on the Moon. A coma is a feature of all comets that approach the Sun closely, for example comet 8. P Wild (nucleus 4 Km diameter) had a coma of 5. Km and 1. 03. P Hartley had a coma of 1. Km. The Great Comet of 1. Sun. We survived them all (and 1. P Hartley came nearly twice as close as Elenin will), and we will survive Elenin without incident. But I Can See a Picture of it in Wiki. Sky, it’s HUGE! That is the carbon star CW Leonis. Is Elenin a Moon of a Brown Dwarf Star? No. But Brown Dwarf Stars are so Cold, you Can’t See Them. No, coldest detected so far is ~3. K (about the temperature of a hot cup of tea), the the warmest are around 2. K, and most range between 5. K. They may not produce much visible light, but they reflect light. Jupiter has a composition similar to those of Brown Dwarf stars. Jupiter’s cloud tops are a chilly 1. K and it reflects light just fine. Any Brown Dwarf in the inner solar system would be painfully obvious. Will Going Through the Comets Tail Affect Us? No, should the rather small tail of Elenin actually pass over us, it’s doing a pretty good imitation of a vacuum (about 1. We have been through bigger and denser comet tails before with no effect whatsoever (especially the Great Comet of 1. Why isn’t Comet Elenin in the News? For the same reason that the other 1. The News is only interested in comets that are spectacular, readily visible to the unaided eye or are being visited by spacecraft. Comet 2. 00. 9 P1 will be as bright, if not brighter than C/2. X1 Elenin, but that’s not in the news either. Amateur and professional astronomers are watching comet Elenin and others avidly, but the news channels don’t care about our obsessions with faint fuzzies. Why Can’t I Find Information of Elenin at the NASA Website? Because NASA is not the arbiter of all things astronomical. You won’t find information on C/2. P1, C/2. 01. 1 C1 or any of the faint comets discovered during 2. NASA does have information of comets that its spacecraft have visited, or are interesting in some other way, but it’s not an exhaustive comet site like Cometography or Aerith.(editor’s note, NASA and JPL’s Near Earth Object Office did publish an article about Comet Elenin in May, 2. Earth.)I Saw Comet Elenin Near the Sun in August 2. Now: In August 2. Elenin. If you are seeing something bright near the Sun in the morning sky now, it’s Venus. How Can I Tell What IS in the Sky and Avoid The Venus Confusion? For freeware standalone programs there is Cartes du Ciel and Stellarium (my favourite). For Web based solutions Skyview Cafe, Sky- Map and Google. Earth (KMZ file here) all work. Where Can I Find Orbital Elements for Celestia or Stellarium? Here. Where Can I Find Images of Elenin? Here, and here and a nice image of C/2. X1 near to NGC 3. I have Photographed/ Seen a Photograph of a Double Sun, is this Elenin? It’s lens flare.
