research paper published in the journal Nature astronomy The Dec. 8 issue said a team of astronomers from several research institutes across the U.S. Revealing the results of the latest study on strange planets. “Janssen” (Janssen) or 55 Cancers e It was found to have a very hot temperature of nearly 2,000 degrees Celsius until it was dubbed as “Planet Hell” because it resembles the hellish atmosphere that many novels have described. And this planet also takes just 18 hours to orbit the central star.
Planet JansenIt is an exoplanet about 40 light-years away from Earth and is a satellite of a star. “Copernicus” (Copernicus), but the orbit of this star is very close to the star. Which is closer than the distance between the earth and the sun up to 70 times, making this planet appear there is lava flowing down The core is a diamond and ocean of molten lava on the surface. And the planet was officially called that. Zacharias Janssen Associated with the invention of the first optical telescope.
55 Cancers e o Planet Janssen Orbit closer to the central star than the Earth. 70 timesCompared to our “Sun”, the planet makes only one orbit. 18 hours Compared to the Earth which takes 365 days to complete its orbit.
The study of a planet that has been dubbed “Planet Hell.” A team of astronomers used the Lowell Discovery Telescope in Arizona. Measuring various details during the phenomenon of “transit” (transit) or the passage of the planet in front of the star. The change in starlight intensity can indicate its properties.
However, Dr. Lily Zhao, lead research scientist in the Flatiron Institute’s Center for Computational Astrophysics, said what they were most interested in in the study was the strange orbit of the planet Janssen. It seems that in the past this star formed in a region far from the central star. But there was a force that gradually attracted him. it later approached the star’s equator
Dr. Zhao explains that this is the star system occupied by Janssen and four of its satellites. different from our solar system Because each satellite does not orbit in the same plane. This complicates the gravitational pull stars exert on their hosts and on each other. This may be why Janssen’s orbit is getting ever closer to its star.
