The planet orbits within the “conservative” habitable zone around its parent star, which could give it the right temperature for liquid water to form on its surface.
“For there to be surface water, of course, other factors would have to coincide, especially a suitable atmosphere. But the conservative habitable zone – a narrower and potentially stronger definition than the broader “optimistic” habitable zone – puts it in a prime position, at least based on the rough measurements made so far. “The smaller planet could be only slightly larger than Earth and could also live just inside the conservative habitable zone,” the statement reads.
He further stated that ‘Super Earth’ completes a full orbit in just 19 days. The parent star of ‘TOI-715 b’ is a red dwarf, smaller and cooler than the Sun.
“Several of these stars are known to host small, rocky worlds… These planets have much closer orbits than those around stars like our Sun, but because red dwarfs are smaller and cooler, the planets can group closer together and still be safe within them. habitable zone of the star,” he stated.
The new planet was found with the help of the Transiting Exoplanet Survey Satellite (TESS).
He said TOI-175 b has joined the list of habitable zone planets that could be examined more closely by the Webb telescope, adding that much will depend on other properties of the planet, including “how massive it is and whether it can be classified as a ‘water world’, making its atmosphere, if present, more prominent and much less difficult to detect than that of a more massive, denser and drier world, which is likely to keep its atmosphere in profile “lower closer to the surface.”
