A Quarter of Sun-Like Stars Host Earth-Size Worlds
astroengine writes "Although there appears to be a mysterious dearth of exoplanets smaller than Earth, astronomers using data from NASA's Kepler space telescope have estimated that nearly a quarter of all sun-like stars in our galaxy play host to worlds 1-3 times the size of our planet. These astonishing results were discussed by Geoff Marcy, professor of astronomy at the University of California, Berkeley, during a talk the W. M. Keck Observatory 20th Anniversary Science Meeting on Thursday. '23 percent of sun-like stars have a planet within (1-2.8 Earth radii) just within Mercury's orbit,' said Marcy. 'I'll say that again, because that number really surprised me: 23 percent of sun-like stars have a nearly-Earth-sized planet orbiting in tight orbits within 0.25 AU of the host stars.'"
PS 1 A.U. is the distance of the Earth to the Sun, just in case you didn't/don't know.
Doesn't that make us "earthists"? It's like the Interstellar equivalent to the Imperial system.

And now you've said it four times. You said the same thing four times. Four times. The entire summary is just the same statement made four times.
