As I recall, it's also higher in 'metals' than average, so there's a
reasonable chance that worlds around other F-K dwarfs will tend to be
less dense, and that the standard Traveller world generation system,
which places Earth as somewhat larger than average, may be correct.

Also, though not as pronounced, this means Earth will tend to be
somewhat high in heavy metals for most aliens, and that Terran organisms
will need extra 'heavy' metals added to their food, soil, etc. to thrive.
