They discover a small exoplanet almost as dense as iron | Digital Trends Spanish


A team of astronomers discovered an exoplanet smaller than Earth but almost as dense as iron. Indeed, most of it, about 86 percent, is made of this material.

It is about GJ 367b which is relatively close to our planet, since it is 31 light years away.

For now astronomers do not know if the exoplanet could be habitable, although they see it as something difficult, they do not know how it would have formed.

Meanwhile, its host red dwarf star is so close that an orbit takes just 7.7 hours and the radiation is so intense that it would reach 2,732 degrees Fahrenheit.

“That’s enough to melt any metal and rock, and it certainly wouldn’t allow life as we know it. Presumably there will be no colonization mission as a result, ”says an article by Engadget.

According to astronomers at the Planetary Research Institute of the German Aerospace Center, GJ 367b is the smallest exoplanet from which scientists have been able to determine its composition.

“It seems to have similarities to Mercury. This places it among the terrestrial or rocky planets smaller than the Earth and makes the research take a step forward in the search for a ‘second Earth’ “, states part of the study that was published in Science.

The team in charge of the discovery was able to determine that the planet is just over 9,000 kilometers in diameter, with a density of 8,106 grams per cubic centimeter.

According to scientists, this discovery also highlights the ability that astronomers now have to accurately measure the mass of planets smaller than Earth.
