Exoplanet 55 Cancer from several names, but A rocky orb located 40 light years from Earth is known for the reputation as “hell planet.”
This super-Earth, so called because it is a rocky planet eight times the size and twice the width of Earth, is so hot that it has liquid lava on its surface that reaches 3,600 degrees Fahrenheit (1,982 degrees Celsius).
The exoplanet’s interior would also be full of diamonds.
The planet is hot enough to be compared to Star Wars wash the world Mustafar, the site of the battle between Anakin Skywalker and Obi-Wan Kenobi in “Revenge of the Sith”, and where Darth Vader later established his fortress, Vader’s Fortress.
The planet, formally named Janssen, but also called 55 Cancer e or 55 Cnc e, orbits its host star Copernicus so closely that it completes an orbit in less than one Earth day. One year of this planet lasts about 17.5 hours on Earth.
The incredibly tight orbit is why Janssen has such hot temperatures — so close that astronomers have doubted it — as it nearly hugs the host star.
Astronomers wondered if the planet had ever been so close to its star.
The team of researchers used a new instrument known as the EXPRES or EXTREME PREVENTION spectrometer to determine the nature of the planet’s orbit. The findings may help astronomers gain new knowledge on the formation of planets and how these celestial bodies evolve. orbit
The tool was developed by a team led by Yale University astronomer Debra Fischer and established the Lowell Discovery Telescope at the Lowell Observatory in Flagstaff, Ugly the spectrometer was able to measure small shifts in the star from Copernicus to Janssen moving between our star and the star — like when the moon blocks the sun during a solar eclipse.
Researchers at Janssen have determined that the orbit is an equinoctial star. But the planet hell is not the only planet of Copernicus. Four other planets occupy different orbits of the star system.
Astronomers believe that Janssen’s oddball orbit began when the planet initially began in a cooler and more remote orbit before drifting closer to Copernicus. Then, the gravitational pull from the star’s equator was changed to Janssen’s orbit.
The study’s findings were published in the journal Nature Astronomy on Thursday.
“Astronomers expect that this planet formed much more distantly and then spiraled into its current orbit,” said Fischer, the study’s senior author and the Eugene Higgins Professor of Astronomy at Yalentin, in a statement. “That passage of the planet could have kicked it off the star’s equatorial plane, but this event shows that the planet is holding tight.”
Although Janssen was not always so close to the star, astronomers have always concluded that the exoplanet is hot.
The planet “was probably so hot that nothing could survive us on the surface,” study lead author Lily Zhao, a research fellow at the Flatiron Institute’s Center for Computational Astrophysics in New York, said in a statement.
Once Janssen moved closer to Copernicus’ planet of the underworld became even hotter.
Our solar system is flat like a cinder block, where all the planets orbit the sun in a flat plane, because they all formed from the same orb of gas and dust that once orbited our sun.
When astronomers studied other planetary systems, they found many of them to be planets orbiting in a flat plane, which begs the question of how our solar system is the only one in the universe.
Such data could provide more information about how common Earth systems and environments may exist in the universe.
“We’re trying to find planetary systems similar to ours, and to better understand the systems we know about,” Zhao said.
The primary purpose of the EXPRES instrument is to spot terrestrial planets.
“Our accuracy with EXPRES today is more than 1,000 times better than what we had 25 years ago when I started working as a planet hunter,” said Fischer. “The measurement of better precision was the first goal of my life because it allows us to detect the smaller planets that are analogues of the Earth we are looking for.”
