NASA’s Kepler mission has discovered a new planetary system that is home to the smallest planet yet found around a star like our sun, approximately 210 light-years away in the constellation Lyra. Credit: NASA/Ames/JPL-Caltech Artist’s Concept of Kepler-20e, one of two Earth-sized p...
Kepler-186f is the first Earth-sized planet in thehabitable zonedetected by the Kepler space telescope. This planet is the outermost of the five planets transiting Kepler 186, a 0.47 solar radius, main sequence M1 star with a surface temperature of 3788 K. The inner four planets of this sy...
Kepler-186f was detected with an additional year of data (Quintana et al. 2014 ). Figure 1 shows an artist's rendering of this planetary system. Kepler 186f: First Earth-Sized Planet in Habitable Zone, Fig. 1 An artist's rendering of Kepler 186f comparing to the inner Solar System (...
The Kepler-186 system is home to Kepler-186f, the first validated Earth-size planet orbiting a distant star in the habitable zone—a range of distances from a star where liquid water might pool on the surface of an orbiting planet. The discovery of Kepler-186f confirms that Earth-size ...

Although the size of Kepler-186f is known, its mass and composition are not. Previous research, however, suggests that a planet the size of Kepler-186f is likely to be rocky. "We know of just one planet where life exists — Earth. When we search for life outside our solar system we ...

For example, the diameter of Earth is only 1/109 that of the Sun, so that, for an outside observer of the solar system, the passage of Earth would dim the output of the Sun by only 0.008 percent. In addition, a planet’s orbital plane must be aligned to pass in front of the ...
