Due to the diameter being 60% larger than Earth's diameter, Kepler-452b's ESI score[0] cannot be any higher than 0.85.

It might not be the most earth like exo-planet as Kepler-438b[1] has an ESI score of 0.88.

In the article they mention that Kepler-438b is likely subject to extreme solar radiation during flares because it's so close to its star. That would make it poor candidate despite scoring high on the ESI scale.

Wow, closer than 452b to us and similar size, have we done any focused listening in its direction yet?
