Among the exoplanets discovered in the past decades, there are two dozen who benefit better conditions for life than our earth. Three astronomers have come to this result, which have formulated how superhabitable worlds in their opinion had to look like. They are planning to search for such exoplanets and explore them, not to explore the earthilliest. Although not all their candidates do not require any requirements, but with koi 456.04 name a system that works quasi a mirror image to the solar system. Only the exoplanet there has not yet been confirmed, it is a so-called candidate.
Also the earth was already good friendly
As the researchers in the trade magazine astrobiology exports, it could be referred to as anthropocentric and geocentric, to ame that there are no places in our galaxy, which are still more infantable than our earth. Because our homeland has shown very different faces in the course of their history and is as "snowball" once not only much more inhospitable, but in carbon about it is already much more caring than today. How studen manager dirk schulze-mugs explores from the technical university of berlin now, he and his colleagues have set up prerequisites, which had to have an exoplanet had to be more vital than our homeland.
Superhabitable exoplanets were therefore allowed to find an orange dwarf especially in orbit, as these stars become clearly age than about our sun. The star should therefore be between funf and eight billion years old. An exoplanet around him should be about one and a half times as massif as our earth and about 10 percent gross. The average temperature is better 5 degrees celsius high than us. The atmosphere should be wet, more oxygen and otherwise containing reaction strain gases like nitrogen. Land and water should be scattered on the surface. Helping was a large moon in a medium distance, plate tectonics as well as a strong magnetic field.
For obvious life possible better
Overall, scientists have found 24 exoplanets based on these parameters superhabitable. But not even all of them are constantly being confirmed, it could also be traces in the data of the nasa space telescope kepler, which drove to the crime. In addition, a series of parameters can not be checked at all because the exoplanets are too far away and can not be determined approximately whether there is platenectonics. Finally, none of the most promising sky corkers is closer than 100 light years. Nevertheless, the astronomers are planning to prefer superhabitable against the exoplanet research superhabitally opposite.
the ever-gebling exoplanets – deemed and ungent (*) – in a habitable zone.
