At some point, we can’t keep referring to the first Earth-like world to be found in the habitable zone of a star that is similar to our sun as “Kepler 452b.” For a “close cousin,” although 1,400 light years away, we need a more familial name. Not a telescope trademark.
We know the Kepler temperatures are right for water–an essential element for life as we know it. Who knows? And because it’s 60 percent bigger than Earth, why not “Gearth?” Hey, it’s our call, and the really cool appellations like Mercury, Venus, Jupiter and Saturn are already taken.
