The search for a “second earth” continues. New “suspect” exoplanets appear, but the discovery of the Max-Planck-Institut in Göttingen is especially interesting.

Göttingen – A new discovery is highly interesting: “KOI-456.04” is almost twice as large as the earth and orbits a sun-like star at a distance, the life-friendly temperatures on the surface and is not so far from the Earth far – 3140 light-years. This discovery by a research team made up now Göttingen.
“Second earth” of the Team in Göttingen, discovered
Was discovered in “KOI” by a Team under the leadership of the Max-Planck-Institute for solar system research (MPS) in Göttingen. With space telescopes such as COROT, Kepler (2009 to 2013) and TESS Researchers have discovered in the past 14 years, more than 4000 planets around distant Star circles.
Among them, some of which, such as Earth mainly made of Rock exist and where pleasant temperatures are likely to prevail. KOI.456.04 is 1.9 times the radius of earth is comparatively large compared to some other Planetconsidered to be life-friendly.
Discovery in Göttingen: “So, it’s like no other Pair of star-and Planet”
“But, in combination with its sun-like host star, Kepler-160, the System appears to be the Combination of the sun and the Earth like no other Pair of star-and Planet that we know of,“ says Heller (MPS Göttingen). Accordingly, pleasant conditions could prevail:

The amount of light that hits KOI-456.04, equivalent to 93 percent of earth’s value; if the atmosphere of the Planet surrounds, would be measured, on average, for beings quite endurable temperatures of five degrees Celsius, ten degrees less than on the average on the earth.

Rule tolerable temperatures in Göttingen have discovered a “second earth”?
“But in order to assess how life-friendly Planet, you have to have the corresponding star in sight,” says René Heller of MPS Göttingen and first author of the study published in the journal Astronomy & Astrophysics. Practically all known worlds that are about as big as the Earth and where moderate temperatures prevail, circles namely red dwarfs.
Stars of this type exist for a very long time, they emit mainly infrared light, are light, weakly – and well-the scene of massive eruptions. Another drawback is Tolerable temperatures would be the only planet to rule, in very small intervals around these Star circles. The enormous appeal, but also for the enemy would be.
Researchers from Göttingen: Similarity in Central stars of
“It is, therefore, doubtful whether erdgroße planet provide red dwarfs favorable conditions for the Emergence of life,” the researchers Göttingen.
With a Radius of about 1.1 solar radii, a surface temperature of 5200 degrees Celsius – just about 300 degrees less than that of the Sun and an almost sun-like brightness of the star our looks like an Image of the Central star Earth to.
The discovery of the exoplanet KOI-456.04 orbiting the star Kepler-160 suggests we should more aggressively look for habitable planets around sun-like stars.https://t.co/OU6S5mP66E pic.twitter.com/wTIzZPZk7c

International Team from Göttingen for years in search of “second earth”
The German-American Team from Göttingen took brightness measurements of Kepler-160, therefore, again. In the past few years, René Heller and his colleagues have developed a method with which extremely small, previously overlooked Planet detect. Already 18 such worlds had the researchers previously in the data of the Kepler telescope discovered.
They were successful: With a Radius of 1.9 times the radius of earth and an orbital period of slightly more than 378 days, the a of – KOI-456.04 is likely to be a of the exciting world of Rocks. You circled within the ring-shaped region around the star in which life-friendly temperatures on our Earth to expect from are, according to the researchers Göttingen.
