According to NASA's website news, 24 am, astronomer's first confirmed discovery is located on the "habitable zone," the volume of the closest Earth-size planets (code-named "Kepler-452b"), which is looking at another human an important milestone on the road to Earth satellites. "Kepler-452b" The discovery of extrasolar planets has confirmed that the number increased to 1,030.
l
habitable zone refers to the distance from the star the planet right area, in this area, the star passed to moderate the heat of the planet, neither too hot nor too cold, to maintain the presence of liquid water.
Kepler-452 stellar system, compare the size of Kepler -186 stellar systems and solar system. Orbital radius of planet Kepler-452b 1.05 astronomical units, almost the same distance from Earth to the sun, orbital period of 385 Earth days.
"Kepler-452b" located 1400 light years of the Earth "Cygnus" direction, the volume is only 60% larger than the Earth. Orbital period of 385 Earth days, a week's time the sun than the Earth around 5% more. Its central star surrounded regardless of size, brightness are very similar to our sun, aged about 60 billion years old, a large 1.5 billion years older than the sun.
Currently, the "Kepler-452b" the quality and composition is unclear, according to previous studies have suggested, like the volume of the planet is likely rocky planets may also have a thick atmosphere and a lot of water, very You may still have active volcanic activity.
