Super-Earth Has Temperatures of 800°F, Glowing Lava Rivers

No day or night, the heat is quite strong, causing the lead to melt and glittering rivers of lava: this is a typical day on the hellish landscape Gliese 486b, from the recently discovered exoplanet nearby star Gliese Circles 486. This planet is rocky and is about three times the mass. Of the Earth, making it a type known as super-Earth. But it is so hot that the conditions there are quite different from it.

This planet is so close to its star that only 1.5 Earth days live in a year. Although this star is faint and colder than our Sun, the planet orbits just 1.5 million miles and is happily closed, meaning that one side of the planet always faces the star. This increases the temperature further, reaching a surface temperature of 700 Kelvin (800 ° F).

Researchers believe this means that the planet will appear more like Venus than Earth, with hotter and drier landscapes and rivers of glowing lava. There is probably very little atmosphere, because the heat emanating from the star will work to remove it, but the gravity of the planet helps to maintain some atmosphere.

The possible existence of a thin but present atmosphere makes this planet an excellent candidate for research because it allows scientists to test their theories on atmospheric models for rocky planets. “The discovery of Gliese 486b was a stroke of luck,” in a statement, co-authored by the paper, Jose A. of the Centro de Astrobigolia in Spain. Caballero said. “One hundred degrees warmer and the entire surface of the planet will be lava. Its atmosphere consists of evaporated rocks. On the other hand, if the Glisee 486B was hundred degrees colder, it would have been unsuitable for follow-up observations. “

Researchers now want to use the upcoming next generation telescope to study the planet and try to peer into its atmosphere to see its structure. “The proximity of this exoplanet is exciting because it will be possible to study it in more detail with powerful telescopes such as the upcoming James Webb Space Telescope and extremely large telescopes of the future,” said Tiffan Triffnov, lead author of the Max Planck Institute for Astronomy. .

“We can hardly wait for new telescopes to be available. The results will help us understand how well rocky planets can capture their atmosphere, what they are made of and how they affect the energy distribution on the planets. “
