[AstroPy] Wrong earth mass in astropy.constants

Therein lies the problem – who decides on the “best accepted value”? My initial thought would be to use values of constants defined by appropriate authorities, such as NASA, AAS, or IAU. But those values will always (and with good reason) lag behind the “latest value”. I think (this is just IMHO, of course) that official, vetted and reviewed values from trusted authorities should be used for AstroPy – and only such values. If a given user needs a more recent value, they can simply override it in their own code (and document said change, of course).

But shouldn't the current version reflect latest value of constants, while versioning is being applied? It seems "current value is different from previous version" is lesser of a problem than "current value is different from current best accepted value"
