"The star [Kepler-186] is about half the size and about half the mass of the sun, so it's dimmer than the sun," said NASA and SETI scientist Elisa Quintana, lead researcher of the group that ...

The planet Kepler-186f is the fifth planet of the star Kepler-186, 490 light-years away. The planet has 1.11 times the Earth's mass. Its radius is 1.1 times that of Earth. Kepler-186f orbits at 32 ...

The new world is the outermost of five Earth-size planets discovered circling a red dwarf star called Kepler-186, which is about 500 light years away. Because the star is cooler than our sun ...

The planet is one of five worlds orbiting a dwarf star known as Kepler-186 some 500 light years away in the constellation Cygnus. The other four worlds were discovered earlier in the Kepler data ...

Theoretical models predict most worlds this size should be rocky. The orbit of the exoplanet brings it around Kepler-186 once every 130 days. The planet lies at the outer edge of the star's ...

Circling a star about 500 light-years away, planet Kepler 186-F may be the right temperature to allow liquid water to flow on its surface. Hari Sreenivasan talks to Tom Barclay of NASA Ames ...

Kepler-186 is an “M-dwarf” star 795 light years away that is smaller and cooler than the Sun. It is orbited by a family of five known planets. Kepler-186f, the latest to be discovered ...

This size and scale of the Kepler-452 system compared alongside the Kepler-186 system and our solar system. By comparison, Kepler-186 is a miniature solar system that would fit entirely inside the ...

Kepler-186f is about 580 light-years away, orbiting the red dwarf, Kepler-186. It orbits its star every 130 days and is around the same size and mass as the Earth. Kepler-186f was the first planet ...

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 ...

One of five planets orbiting a red dwarf star (called Kepler 186), Kepler-186f is 1.1 times wider than Earth. That means it's almost certainly a rocky planet too. The researchers estimate its mass ...
