The discovery of Kepler-186f confirms that planets the size of Earth exist in the habitable zone of stars other than our sun. While planets have previously been found in the habitable zone, they are all at least 40 percent larger in size than Earth and understanding their makeup is challengi...
Kepler-186f NASA/JPL-Caltech Kepler-186f, the first validated Earth-size planet to orbit a distant star in the habitable zone, a range of distance from a star where liquid water might pool, on the planet's surface, is seen in a NASA artist's concept released April 17, 2014. ...
.Kepler-186f is very important because it is the first planet that is the same temperature(温度) and is almost the same size as Earth,"可知,该星球的温度与地球相同,且大小与地球类似,是一颗类地星球,因此B、D选项描述正确;根据Scientists don't know anything about the air of Kepler-186f,but it...

The five planets of Kepler-186 orbit a star classified as a M1 dwarf, measuring half the size and mass of the sun. 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...
