Researchers found that this planet is eight times closer to its star than the distance of the Sun from Earth. At the same time, its size is equal to the planet Varuna.

Scientists from the US space agency NASA have discovered a ‘cold’ exoplanet located 90 light-years away from Earth. According to a study published in Science Daily, researchers from NASA’s Jet Propulsion Laboratory and the University of New Mexico discovered the exoplanet ‘TOI-1231 b’, which is orbiting an M dwarf star. It is also known as red dwarf. Scientists have been able to characterize the star and measure both the radius and mass of TOI-1231 b.
According to the study, researchers found that this planet is eight times closer to its star than the distance of the Sun from Earth. At the same time, its size is equal to the planet Varuna and it completes the orbit of its star in 24 days. The team found that the temperature of the planet TOI-1231 b is the same as that of our planet, because its star, or say the Sun, is less powerful than our Sun. Its atmosphere is about 330 Kelvin, or 140 degrees Fahrenheit, which makes TOI-1231 b one of the best and smallest exoplanets for atmospheric studies yet discovered, they said.
There may be evidence of the presence of water!
Researchers said that the density of the exoplanet is low, which suggests that it is not a rocky planet like Earth, but a gaseous planet. However, he said that they do not yet know the exact composition of the planet or its atmosphere. Researchers said that there is a possibility that high clouds are present in the atmosphere and there is possible evidence of water. Diana Dragomiro, assistant professor in the Department of Physics and Astronomy at the University of New Mexico, said TOI 1231 b’s low density indicates that it is surrounded by a substantial atmosphere rather than being a rocky planet. But we do not know about the structure and extent of this atmosphere.
The atmosphere of the planet may be something like this
Professor Diana Dragomiro said that TOI 1231 b could have a large hydrogen or hydrogen-helium atmosphere or a dense water vapor atmosphere. Each one of these points to a different origin. This will help astronomers understand how planets orbiting M dwarf stars form compared to planets orbiting around our Sun. There. If water clouds are discovered on TOI 1231 b, then it is going to be a big discovery for humans.
