Researchers have described the conditions on the planet, called 2-141b, which are located About 210 light-years from Earth. It orbits very closely around its star, which is slightly smaller than our Sun.
This “lava” planet completes one revolution in about six or seven hours, grazing the surface of the star and damaging it through almost the same space.
In contrast, Mercury, the closest planet to the Sun in our solar system, takes 87 days to orbit the Sun.
About half of the planet is molten magma, said lead study author Mars Griang Nugien, a doctoral student at York University in Toronto. “The atmosphere created by the steamy rocks spreads around the earth.”
Silicon dioxide or quartz evaporates, creating clouds and rain, or rain on molten surfaces below, he said.
A strange planet
Exoplanet – a planet that orbits a star other than the Sun – Astronomers measure the difference in light when a planet is in its front orbit in front of its back. When observed on Earth through a telescope, the star appears dim when the planet is in front of it, while slightly obscuring the Earth’s view.
Scientists have discovered thousands of worlds outside our solar system using this method. In many of them, there are melting surfaces that drive such dramatic swings in the planet’s climate and structure. In the available literature, Nguyen observed that astronomers have observed only a handful of lava planets.
Exoplanet At 2-141b there are clocks that move at a clock speed (approx., 000 kilometers), and its magma is estimated to have a depth of 86 86 miles (1 miles0 kilometers) in the ocean, according to Nguyen’s calculations.
Extraordinary winds dominate one side of the planet, but the other side is totally absent.
With a temperature of 200,000 degrees Fahrenheit or 1,000,000 degrees Celsius. It is an atmosphere composed of silicon dioxide on the warm side, more commonly known as quartz.
Because K2-141b orbits very closely in the bright glow of its star, about two-thirds of the world is illuminated at any one time. One-third is dark, forming a cold planet with a temperature of minus 392 degrees Fahrenheit or minus 200 degrees Celsius.
Compared to the planets in our solar system like Earth and Jupiter, the splitting of that two-thirds light / one-third darkness is unusual, where half of the earth will be lit by the sun at any time.
“It’s a planet that doesn’t mean much. There’s nothing like it in our solar system,” said Nicholas Cowan, associate professor of physics and Earth and Planetary Science at Montgomery University in Montreal.
Lava planets are quite rare, Kovan noted – only one out of 1,000 stars will be able to host. But given the enormity of the universe, there could be millions upon billions of worlds.
Studying such an alien planet could pay dividends, helping scientists understand the version of the situation that existed on Earth during its formation, when it was also covered in molten lava millions of years ago. Looking closely at the lava planet can give answers to how it – and Earth – came into being, Kovan said.
“It’s a strange, naked, rocky core that meant a big planet.”
Search for another earth
Jonathan Fortney, a professor of astronomy and astrophysics at the University of Santa Cruz, said in an email that the lava planets have definitely captured people’s imagination and are a rare, but very real class of planets. “Unlike an Earth-like planet, the material that makes up this planet’s atmosphere is literally the same material that makes up the crust.”
Fortney compared K2-141b and similar lava planets with Pluto, which is rich in nitrogen in the form of ice in the crust and gas in its atmosphere.
“Planets like these open up opportunities to use the atmosphere (which is always easy to study) and to learn something about crust formation, which is more difficult to study,” he said via email.
Both Nguyen and Cowan said they hope to continue studying the lava planet, which will soon be observed with next-generation devices from NASA’s James Web space telescope, which is set to launch next year.
The new space telescope will be able to take high-resolution spectrographs of the planet and understand more closely the structure of its interior, oceans and atmosphere.
“This is an additional step in trying to find Earth 2.0. It is the end of space exploration.”
