Great oceans on Proxima B, we know where to go next.

Proxima B for several months spends awake astronomers from all over the world, thanks to the possibility of life there. Recall that this planet is similar to the Earth, because it is the planet of stone, is located at such a distance from its star that its surface can be water in the liquid state, and therefore is in the so-called “the zone of residence”

The latest study scientists at the French National Centre for Scientific Research (CNRS) reveal that the existence of the Proxima (B) oceans is very likely. Yet we were unable to observe, how big is this planet, because this is by measuring how much light blocks the planet passing between its star and Earth, but this has been calculated on the basis of advanced computer simulation.

It follows that the radius of the planet is from 94 to 140 percent of the radius of the Earth, and on average it is 6371 km. By adopting the minimum diameter of the order of 5990, scientists from the CNRS, they concluded that the planet must be very dense, with a metallic core which is 2/3 of its weight, which is surrounded by the Rocky mantle.

If it was water in the liquid state, it is not more than 0.05% of the mass of the planet (for the earth it is 0.02%). However, if it has a diameter of 8920 miles, and there is water, is the mass of the planet is equally divided between solid and water. Most likely the second scenario is true, which means that Proximę b cover one ocean with a depth of 200 kilometers.

What is most interesting, studies show that in both cases, the planet can have the atmosphere, which can do it potentially suitable for residence. So even if not currently develops there some form of life, it is the only known us an extra-solar planet, which is so great place to its creation.
