New Planet Will Replace the Earth

A number of planets in the universe like the earth. Experts suspectsome of which can be occupied (David A. Aguilar, CfA)

    The technology allows humans to roam the Earth out to investigate further the formation of the universe. Various studies have concluded a number of exploration and provide new hope for the planet habitable, to replace the increasingly crowded Earth.Some of the solar system were found similar to the Milky Way, where the Earth's orbit. Even the number of planets found are also believed to be similar to Earth. Scientists and astronauts suspect human life can go on these planets.So far, there are some planets like Earth published and is expected to sustain human life. Here are a few:A. Planet GJ 667CcThe planet is called Earth-like the best candidate. Quoted from Dailymail, the detected planets through a telescope from Earth, the rocky like the Like the Earth we inhabit it. In addition, he is also orbited by "residential zone" with a suitable temperature for the presence of water on the surface. 
    Surface temperature may be similar to Earth."The new planet is the best candidate to provide water, and perhaps life," said lead study, Guillem Anglada-Escudé, February 2012.The planet was detected in the European Southern Observatory telescope has a weight of 4.5 times the Earth and orbits a star in the so-called GJ 667C with a distance 22 light years from Earth.In the context of the galaxy, he's our neighbor.Reported by the Telegraph, the planet orbits the star with a period of 28.15 days, almost the same as the earth to the sun."The planet is orbiting the three star system. But two other very much. Both will look pretty in the sky," said Steven Vogt, a professor of astronomy.Two other star is an orange dwarf star. There are three planets orbiting a nearby star.2. Planet KOI 326.01Volume and the planet has a diameter smaller than Earth with a slightly lower temperature than boiling water. In terms of size, Earth-like planet.KOI 326.01 Planet was first arrested by the Kepler telescope.The telescope is working to detect extrasolar planets (outside our solar system). He was able to observe 150 000 stars nearest Earth in space.As far as the observations of KOI 326.01, a planetary scientist from NASA Ames Research Center William Borucki said, "This is a small object, a small candidate.""Astronomers were not even knowing what the size of its parent star. Therefore, it is difficult to know the characteristics of planets similar to Earth's. Until now, no further confirmation," he said, which is also responsible for the Kepler Science Team Leader, February 2011.There are estimates that one out of 200 stars in space must be a planet that has a habitable zone living, or resembling a life like Earth.KOI 326.01 Planet is one of them?That remains a mystery. But, according to some scientists, Earth-sized planet that is one of the planet suitable for life alternatives inhabitants.3. Planet Gliese 581gThe observation MW Keck Observatory in Hawaii, United States, for 11 years to fruition. The scientists found a planet that is most similar to Earth called Gliese 581g, in September 2010.Planets whose size is similar to Earth's orbit and is in the middle of the "habitable zone astrology". Researchers also found a liquid substance can exist in the planet's surface.This will be the most Earth-like planet that has never encountered before. This is also the first planet inhabited by human beings with the most potential.The most interesting of the two planets is Gliese 581g, he has three to four times the mass of the Earth and an orbital period of just under 37 days. The volume of the mass showed that the planet is likely rocky planet with a given surface. It also suggests that the planet has enough gravity.Gliese 581g is located a distance of 20 light years from Earth, precisely located in the constellation Libra. The position of this planet, one side always facing the star and have hot temperatures that allow people to sunbathe on an ongoing basis during the day. On the side facing away from the star, is in constant darkness.The researchers estimated the average surface temperature of the planet is between -24 and 10 degrees Fahrenheit or -31 to -12 degrees Celsius. The temperature will be very hot when its position facing the star and freezing can occur while the dark.According to Professor Vogt, on the surface of the planet's gravity is almost the same or slightly higher than the Earth, so people can easily walk upright on the planet.4. Kepler System 9Kepler satellite discovered the alien planets, planets that have never been seen before around a star that - like the planets in the solar system around the Sun, August 2010. This finding system called Kepler 9.Observations of Kepler observatory confirmed two Saturn-sized planet orbiting a star - within about 2,300 light years from Earth.Two of the largest planet in this system called Kepler Kepler 9b and 9c - were found to have nearly the same diameter. Both have mass and density as Saturn.However, the two planets are too close to the stars - like our sun, like Mercury, which orbits the Sun. The two planets were allegedly not having a life because it is very hot.The astronauts have yet to find Earth-like planets from Kepler observatory system. If the existence of a third planet like the Earth has been no confirmation that the planet could be the smallest known planet. "We can say, in terms of physical size, this will be the smallest, but we do not know its mass," said Matthew Holman, the staff director of the division of theoretical astrophysics at the Harvard-Smithsonian Center, which confirmed the findings Kepper.Keppler said, the third planet has a radius 11.5 times the Earth and have orbital periods of about 1.6 Earth days - shorter than the Kepler-9b and 9c. The researchers are examining whether the candidates' twin of the Earth "orbiting the same star with the two other planets.But in terms of eligibility for habitation, Kepler-9 system is probably not the right place to look for life. "The planets are as unfit for human habitation," said Holman. Estimated temperature of the two largest planets are very high, about 740 degrees Kelvin (872 degrees Fahrenheit) and 540 degrees Kelvin (512 derajatFahrenheit).5. Kepler Planet 10-bU.S. space telescope discovered a planet outside our solar system is located. Planet looks rocky, like Earth. Unfortunately, the planet is uninhabitable, due to overheating. According to NASA, the temperature on one side of the planet of 2,700 degrees Fahrenheit, or about 1482 degrees Celsius.NASA astronomer, Natalie Batalha, said that the planet is 1.4 times larger size and has a mass of 4.5 denser than Earth.Kepler 10-b orbiting a sun-like star 560 light years and is, or about 9.4 trillion kilometers.6. Planet GJ 1214bPlanet is larger than Earth and has a water content. The findings of a team of Harvard-Smithsonian Center for Astrophysics was published in the journal Nature on Wednesday, December 16, 2009.Measuring 2.7 times larger than Earth, the planet orbits the sun, the smaller and less luminous than the sun in our solar system.Although the planet GJ 1214b likely to have an atmosphere that is too thick and too hot for life forms on Earth, the discovery was a major achievement in the search for life on other planets."The biggest joy because we found a world with a water content around the star is very small and very close, only 40 light years from our solar system," said David Charbonneau, professor of astronomy at Harvard University and lead author of the article in the journal Nature, as quoted from the pages of CNN.Planet GJ 1214b is classified as a "super-Earth" because it is between one and ten times larger than Earth. In recent years, scientists have been aware of the existence of this super planets.Most of the astronomers who found very large, so it looks more like Jupiter than Earth.Charbonneau said, life on planet GJ 1214b is unlikely to be much like life on Earth. "This planet has the possibility of liquid water," he said.7. 100 to planetKepler telescope finds more than one hundred and magnitude of Earth-sized planets. The discovery occurred in 2010, after Kepler scan the sky to discover the existence of planets orbiting stars.These discoveries strengthen the notion of the possibility that Earth humans are not alone in this universe.Astronomer Dimitar Sasselov, as quoted by the Daily Mail, said that the telescope reveals 140 different planets that have a size similar to Earth. "The discovery of this remarkable fulfill the dream of Copernicus," said Sasselov.
