A fresh one in the studio the authors present a super-Earth type exoplanet, writes a ScienceAlert. From a cosmological point of view, the celestial body is close, only 200 light years away. TOI-1075b’s radius is 1.8 times that of Earth, making it one of the largest known super-Earths.
Interestingly, only very few planets with radii between 1.5 and 2 Earth radii have been detected so far. The newly detected celestial body is therefore particularly exciting. TOI-1075b has 9.95 Earth masses, which is too dense for a gaseous planet. Here because Zahra Essacka doctoral student at the MIT Kavli Institute, and colleagues believe the object is a rocky planet, like Mercury, Earth, Mars or Venus.
In 2017, astronomers noticed the lack of rays. Since then, several explanations have been developed for the rarity of celestial bodies between 1.5 and 2 Earth radii.
TOI-1075b was found by NASA’s exoplanet hunting telescope, TESS. The data revealed that the orange dwarf TOI-1075 is orbiting a 1.72 Earth jet object. The celestial body orbits its star very quickly – in 14.5 days.
The team hypothesizes that the celestial body either has no atmosphere or is composed of silicate vapors, possibly hydrogen and helium or carbon dioxide. It is possible that the surface of the object is covered with a huge magma ocean.
The researchers hope that subsequent observations will allow them to learn more about the celestial body. One of the tools of the investigations may be the James Webb Space Telescope, which can also be used to study the atmospheres of exoplanets.
