Closest earth-like planet just 13 light years

An earth-like Alien planet may just be 13 light-years away. NASA’s Kepler space telescope shows 95 exoplanet candidates — planets outside the solar system — circling more than 3,000 red dwarf stars. Astronomers say three of these exoplanets are roughly Earth-size and orbit within zones where water, and possibly life, can exist. Since red dwarfs comprise about about 75 percent of the galaxy’s 100 billion stars, astronomers say there is an estimated 4.5 billion “alien Earths” throughout the galaxy. Researchers estimate the nearest planet similar to our own would be 13 light-years from Earth.
