Wouldn't all that be considered per specific solar system in determining where the goldielocks zone is?
The "goldielocks zone" is determined by the type of star more than anything else. When determining if a planet really is "Earthlike", the planet itself will be looked at as well as it's location in the solar system.
The designation of Earthlike here is somewhat misleading because this planet isn't really "Earthlike". It's has a tidal lock orbit, which is very unearhtlike, and a 37 day orbital preiod (also very unearthlike.
In truth, the planet is being called Earthlike because it has th epotential to have liquid water in the secondary "goldilocks zone" created by the Terminus (which is the divider between night and day on a planet, in cases wher eth eplanet is tidally locked, the terminus is stationary and thus represents the "moderate tempurature" zone).
We also know nothing about it's atmoshpere that I was able to see. If the atmosphere is not earthlike, it might not be habitable for humans. According to the article, it's gravity should be somwhere close to that of Earth, which does make it "Earthlike" in that sense.
From what I can tell, labelling it as "earthlike" is misleading, but it does have the potential of being habitable by humans providing it has the right conditions necesary for human life to exist on it in the terminus (teh right conditions would be many of those that Tashah mentioned).
It is also possible that life evolved on the planet, but technically that is even possible in places that fall outside the are we call the "habitable zone". We have a very limitted dataset with which we are working when we make claims about "habitable zones". We are only looking at one instance of the development of life amongst what may potentially be billions of instances (or it may potentially just be one. We have far too many unknowns to make any definitive claims. It is all speculative).
In other words, we cannot genralize data from a single specific instance to the entire universe. All we can say is that the "habitable zone" was a prerequisite for creating life as we know it here on Earth. We are assuming that Earthlike planets found elsewhere will also have the ability to produce life, but that is not a given, nor are the conditions that were necesary for life on EArth necessarily required fo rthe formation of life in general.
