… for the Next Earth

"About a month ago, astronomers announced they had found a new exoplanet—this one, orbiting in the habitable zone of the nearest star to Earth. Proxima b is exciting because it's nearby, and someday someone might send a spaceprobe to it. Plus, it has a mass close to Earth's—making it more likely to be livable.

But Proxima b is also notable because scientists know its mass at all. Many of the 44 potentially habitable exoplanets have been found by Kepler-style transit searches, which watch and wait for planets to pass in front of stars and eclipse some of their light. But that only gives you a measure of a planet's radius. Proxima b popped out of a different technique, one that, for the most part, hasn't been sensitive enough to see planets like Earth. And advances in that technique—including a new instrument called EXPRES—could improve detection enough for scientists to find and weigh lots of other Earth-mass planets…"

A nice Wiki article on the habitability of planets in binary star systems.
