This planet is so hot that there is a magma ocean on its surface, the temperature of which is about 2000 degrees Celsius.
Scientists have discovered that the planet Janssen wraps around a star’s equator, but its strange orbit suggests that the planet was initially much further away from the star before getting close to Copernicus. Then the gravitational pull from the star’s equator changed the orbit of the planet Janssen.
Speaking of which writes ScienceAlert.
Planet 55 Cancri eo Janssen – this is a rocky world, with a mass exceeding the mass of the Earth by 8 times, and its diameter is 2 times greater than that of our planet. It was always hot. But as she got closer to Copernicus, she got even hotter.
This planet is so hot that there is a magma ocean on its surface, the temperature of which is about 2000 degrees Celsius.
“We already knew that Janssen’s orbit is different from the orbits of the other four planets. But we measured all the orbits of all the planets in this system and now we know that this hellish planet didn’t always rotate so close to the star. This is due to the internal migration of planets. This is a real hell, it’s so hot here that no living organism known to us could survive on this planet,” said Lily Zhao of the Flatiron Institute.
Scientists believe that the internal migration of planets in the Copernican system may be due to the fact that they are not in the same plane of rotation around the star.
Earlier, an international team of scientists discovered two new ones exoplanets, being super-Earths.
These are rocky planets that are larger than Earth in mass, but smaller than Neptune. The discovered planets revolve around a red dwarf, the temperature of which is half that of the Sun. But one of them is in the life zone and is of particular scientific interest, because there may be an atmosphere and even life.
