The conservative habitable zone is where the planet TOI-715 b orbits its parent star. Red tiny, which are smaller than stars like the Sun, are its parent stars.
NASA scientists have made a significant discovery: they have discovered a planet that may be home to life, nicknamed a “super-Earth.” This planet, known as TOI-715 b, is around 1.5 times wider than Earth and is located 137 light-years from Earth. Its conservative habitable zone orbit around its parent star may “give the planet the right temperature for liquid water to form on its surface.” NASA stated.
Additionally, NASA stated in its report, “Of course, a number of other conditions would need to be met, namely the presence of an appropriate atmosphere, in order for surface water to exist. However, based on the initial measurements conducted thus far, the conservative habitable zone-a more limited and maybe stronger definition than the more expansive “optimistic” habitable zone—places it in the lead. The smaller planet might only be a little bit bigger than Earth and could only be found in the conservative habitable zone.”
The parent star of TOI-715 b is a red dwarf, a star that is smaller and cooler than the Sun. Right now, they seem to be the most viable option for finding habitable worlds. Red dwarfs are smaller and colder than planets orbiting stars like the Sun, so planets may get closer while still staying safely inside the star’s habitable zone.
NASA states that “Those orbits that cross the faces of their stars, or those that are visible to our space telescopes, cross far more frequently due to the tighter orbits.” For planet B, that means once every 19 days, or once in a “year” on this strange planet.”
The list of planets in the habitable zone that the Webb telescope might observe more closely—possibly even searching for signs of an atmosphere-now includes TOI-175 b. A great deal will depend on the planet’s other characteristics.
