There was no uniform standard to bestowing localized names to planets, moons, asteroids, comets and other phenomena in space.
Different states and organizations might agree to one of the many standards supported by different scientific associations, but the Larkinson Clan didn't sign up to any of them. There were no legal constraints that limited the names that it could bestow to newly-encountered planets and moons.
Although the right to name satellites sounded like an impressive way to make a mark in humanity's history, the truth was that there were far too many star systems in the Milky Way and the Red Ocean.
The sheer abundance of satellites to be named reduced the value of bestowing them with artificial labels.
The only instances where naming planets and moons were valuable was when the star system had all of the signs of becoming an attractive destination.
