Earth-Like Planets Fill the GalaxyMichael Moyer
And because of their sizes and orbits, the newfound planets are likely either rocky—like Earth—or watery, NASA scientists said. The two planets are located 1,200 light-years away in a five-planet system orbiting a star dubbed Kepler-62. Called Kepler-62e and -62f, the planets are by ...
So far scientists haven't found aliens(外星人)yet. But they have found an Earth - like planet. Last month, with a big telescope, European scientists found a planet a long way outside the solar system. They say in some ways it is like our Earth. The planet, named Gliese, goes around...

The planets orbit a sun known as "Teegarden's star," which isonly 12.5 light-years from Earth. (A light-year is the distance that light travels in a year, or roughly 6 trillion miles or 10 trillion kilometers.) The two planets look an awful lot like Earth and our neighboring worlds,...
LOS ANGELES, March 22 (Xinhua) -- More than 5,000 planets have been found to exist beyond the solar system, a milestone for astronomy confirmed by NASA on Monday. The 5,000-plus planets found so far include small, rocky worlds like Earth, gas giants many times larger than Jupiter, and...
