Question: This planet is -40to 95 deg bigger than earth and 5 times the gravity. They think its mosty rock and water and has an year of 13 days vs our 365! They say this makes earth like planets 1 in 100 vs the old 1 in a 1000 thats cool news uhh! The tempature is -45 to 95 deg farenheit http://www.youtube.comwatch/?v=5w7NUsBcgyw sorry about bad spelling

It is called Gliese 581c.This Earth like planet is 20.5 light years from us and its sun is a red giant and ten times bigger than ours, and 50 times colder than our sun and it is in the constellation of Libra. The planet is 12,000 miles in diameter compared to our 8,000 miles and it has five times the mass and twice the gravity.The temperature there would vary like Earth,but it's suppose to be about 40degrees Celsius.It takes 13 days to travel around the sun and is only 6 million miles from it compared to our 93 million miles. There is another Earth like planet about 50 light years away and it has a mass of 14 times that of Earth.The sun it orbits is roughly the same size as the planet.It takes only ten days to complete its orbit around its sun and would be to hot to sustain life.Not to much is known about this one at the moment.

10 light years? lol think 50 - 1000 light years http://en.wikipedia.org/wiki/Kepler_(spacecraft)#Extrasolar_planets_detected This question discusses time to the nearest star(about four lightyears), note the speeds discussed in this question are unatainable by a space craft that could hold 10000 residents. http://answers.yahoo.com/question/index?qid=20070814212350AAIc0NB

You're dreaming. This is not plausible for several reasons. Current technology does not make it possible to send a ship that size to another star system. There are no "habitable" planets within 10 light years. Current technology does not allow determining an exoplanet's exact characteristics anywhere near enough to risk sending any kind of manned mission there. A manned "colony ship" would never be sent to another star system based on observations only, for reasons that are obvious. The planet could seem to be habitable, but full of viruses or bacteria that were deadly. It could be bombarded by radiation, from internally or externally. It could be ravaged by earthquakes, volcanoes, or some other form of geologic activity that would make living there impossible. It could be populated by large hostile creatures, or some other civilization not amenable to colonists. There are a million reasons why this would not make sense, the main one being it would be fantastically expensive and draining of resources for the people living on Earth, just at a time when we need them most. Also, your distances make no sense. There are no star systems at distances of 1/4, 1, or 3 light years. There is only one or two within the 5 light year range, and there is no evidence they have habitable planets. Using technology that could be available in the next 100 years, it would take possibly 100 years to get to a star system 10 light years away, and it's difficult to conceive how you'd get 10,000 people to consent to a lifetime on board a space ship with nothing to look forward to but a very long confinement, or how you would arrange breeding and educating enough new people to keep a viable society functioning and the ship running, much less a focused and stable leadership system. An even more poignant question would be, what do you do with the people who can't contribute? It's one thing to select people for a mission like this, you can have the cream of the crop, so to speak, but when you're in interstellar space years in the future, you don't get to pick and choose. Your children will be mostly average, maybe not able to learn the complex knowledge and tasks required to pursue this mission. What do you do with the people who are mentally deficient, unbalanced, or prone to anti-social behavior? How do you stop people from fighting, and forming cliques with their own agenda? Without the many specialized people and institutions available on Earth, this idea doesn't really seem viable.

What do you mean by -40 to 95 deg bigger than Earth? If any planet has 5 times gravity it means it will have more than 5 times atmospheric pressure which would make it very hard for life (if its similar to earth). 13 days per year means either its too close to sun or days are really long in both cases the planet can't have life or liquid water. Either the scientist who are saying this are totally stupid or you've got some wrong information, there is no way to measure presence of liquid water on any planet that is 20 LY away and has approx. 5 times mass of earth i.e. around 2-3 times the size of earth.

The planet, Gliese 581 c (orbits the star Gliese 581), isn't actually known to be Earth-like. It's at the right distance from the star, but we don't really know if it is Earth-like or not. You can be the right distance from the sun, without being Earth-like (The moon, for example. Why isn't the moon habitable? Minimal atmosphere). We know nothing about the atmosphere of Gliese 581 c, if it has one, so we don't know anything about whether or not it is Earth-like.

India! Has India contributed the most to the continuation of the human species on this planet? YES Almost everything known to mankind in the area of science, maths, medicine, metaphysics and astronomy came out of India. for eg: Indians were the first to conduct surgeries & use anesthesia, Indians came up with the concept of zero and the number system, Indians invented algebra, trigonometry and other areas of mathematics, Indians invented Yoga and martial arts, (even though it is wrongly depicted in the west to be a Chinese invention! The Chinese themselves acknowledge that they learnt it from India!) Indians built the first university, invented the first school of medicine - ayurveda, discovered the art of navigation; The list goes on and on and on!! Indians have, by far, made the most inventions and discoveries! Here is a quote from Einstein. "We owe a lot to the Indians, who taught us how to count, without which no worthwhile scientific discovery could have been made!" In fact, on doing further research, I have found out that some of the Europe's greatest inventions and discoveries were actually made in India thousands of years before Europe ever existed! For example, gravity! Isaac Newton did NOT discover gravity, it was discovered at least 2000 years before the British empire existed by an Indian astronomer by the name of Brahmagupta! (I hope I got the spelling right) "The motion of the stars calculated by the Hindus before some 4500 years vary not even a single minute from the tables of Cassine and Meyer (used in the 19-th century). The Indian tables give the same annual variation of the moon as the discovered by Tycho Brahe - a variation unknown to the school of Alexandria and also to the Arabs who followed the calculations of the school... The Hindu systems of astronomy are by far the oldest and that from which the Egyptians, Greek, Romans and - even the Jews derived from the Hindus their knowledge." - Jean Sylvain Bailly (French astronomer) Where can we look for sages like those whose systems of philosophy were prototypes of those of Greece: to whose works Plato, Thales and Pythagorus were disciples? Where do I find astronomers whose knowledge of planetary systems yet excites wonder in Europe as well as the architects and sculptors whose works claim our admiration, and the musicians who could make the mind oscillate from joy to sorrow, from tears to smile with the change of modes and varied intonation? -Colonel James Todd (American pioneer) It will no longer remain to be doubted that the priests of Egypt and the sages of Greece have drawn directly from the original well of India, that it is to the banks of the Ganges and the Indus that our hearts feel drawn as by some hidden urge. -Friedrich Mejer (English statesman) "I am convinced that everything has come down to us from the banks of the Ganges, - astronomy, astrology, metempsychosis,.. It is very important to note that some 2,500 years ago at the least Pythagoras went from Samos to the Ganges to learn geometry...But he would certainly not have undertaken such a strange journey had the reputation of the Brahmins' science not been long established in Europe..." -Francois Marie Arouet Voltaire (French writer and philosopher) Which civilization was the centre of human existence for the longest period of time? DEFINITELY India! India is the world's largest, oldest, and oldest continuous civilization. India was also the wealthiest civilization on the planet for ALL of human history, (except for the 19th and 20th century, of course!) "The multiplicity of the manifestations of the Indian genius as well as their fundamental unity gives India the right to figure on the first rank in the history of civilized nations. Her civilization, spontaneous and original, unrolls itself in a continuous time across at least thirty centuries, without interruption, without deviation." -Sylvain Levi (French Orientalist) Was it the one land that all men desired to see? YES! "India is the one land that all men desire to see, and having seen once, by even a glimpse, would not give that glimpse for the shows of all the rest of the world combined." -Mark Twain
