200 Earth-Sized Planets —The Latest Kepler Mission Findings.
“The most recent Kepler news release from February 28 reveals that the total count of Kepler planet candidates has reached 2321 and 1790 host stars, with 1091 planets emerging in the new analysis. The headline of the findings is profound: “A clear trend toward smaller planets at longer orbital periods is evident with each new catalog release. This suggests that Earth-size planets in the habitable zone are forthcoming if, indeed, such planets are abundant.”
The Kepler catalog database now holds over 200 Earth-size planet candidates and over 900 that are smaller than twice the Earth’s size, which makes for a 197 percent increase in this type of planet candidates, with planets larger than 2 Earth radii increasing at about 52 percent.
Ten planets in the habitable zone (out of a total of 46 planet candidates there) are near Earth in size, and the fraction of host stars with multiple candidates has grown from 17 to 20 percent.”
