How Does NASA’s Found Planet in Habitable Zone Differ From Our Own Earth?

A planet that may support life has been found by the National Aeronautics and Space Administration (NASA); it is situated 137 light-years away, which is not too far away by astronomical standards.

Situated at 137 light-years distant, a little reddish star is relatively close to Earth by astronomical standards, circling a “super Earth” that is ready for more research. A news statement from the American space agency stated, “A second planet the size of Earth may exist in the same system.”

The planet, known as TOI-715 b, is about 1.5 times wider than Earth and completes an orbit, or a year, in just 19 days.

According to NASA, its orbit falls inside the “conservative” habitable zone surrounding the parent star, which may mean that liquid water might eventually exist on its surface.

NASA went on to say that the presence of surface water will depend on a number of additional conditions, chief among them being the presence of an appropriate atmosphere.

“But the conservative habitable zone — a narrower and potentially more robust definition than the broader ‘optimistic’ habitable zone — puts it in prime position, at least by the rough measurements made so far. The smaller planet could be only slightly larger than Earth, and also might dwell just inside the conservative habitable zone,” NASA stated.

“Much will depend on the planet’s other properties, including how massive it is and whether it can be classed as a ‘water world’ – making its atmosphere, if present, more prominent and far less difficult to detect than that of a more massive, denser and drier world, likely to hold its lower-profile atmosphere closer to the surface,” NASA said.
