We cannot understand nature without understanding its extent. This is clear in exoplanetary science. In this context, the ultra-dense planet Gliese 367 b, or Tahai, which orbits its star in only 7.7 hours, is described as eccentric.
Astronomers have been finding the planet since 2021. But new research in The Astrophysical Journal Letters is working to provide improved measurements of the planet’s mass and diameter, and has also found two similar siblings to this planet.
In this context, scientists found “Gliese 367 b” in 2021 when a very weak transit signal was detected from the red dwarf star, and astronomers knew at the time that it was as small as Earth.
As part of the 2021 effort, researchers used the European Southern Observatory’s HARPS spectrometer to determine the mass and density of G 367 b.
In new research published a few days ago, scientists led by lead author Elisa Gofo of the University of Turin found that the planet has a mass of 63 percent of Earth’s mass, and its radius has shrunk to 70 percent. This means that it must be almost pure iron. It is described as being similar to Earth with its rocky cover removed.
This indicated to the agents that the density of the strange planet is twice that of Earth, according to the “Science Alert” website.
