CAPE CANAVERAL, Fla. — Astronomers have discovered a close new world about the size of Earth, where a year lasts just under 10 days.
At a distance of 11 light-years, Ross 128 b is the second-closest planet to be detected yet outside our solar system with surface temperatures potentially similar to ours.
Ross 128 b is very near its star, thus the short orbit. But it doesn’t get broiled because the red dwarf star is cool. The star is also quiet, meaning no radiation flare-ups. That’s encouraging news for seekers of extraterrestrial life. The planet is believed to border the so-called habitable zone.
A team led by the University of Grenoble Alps’ Xavier Bonfils made the discovery using La Silla Observatory in Chile. The findings were reported Wednesday.
NASA’s exoplanet count stands at 3,550.

Just because it is quiet now doesn't mean that it always was. An old star like that might have long since licked the faces of it's planets clean during it's various transitions. That planet could have been sterilised a billion years ago.

It will be again when the sun transitions from fusing hydrogen into helium to making heavier elements at which time it becomes a "red" star and blows up like a balloon, swallowing the Earth .
