planet, official name

This is not really a name; it’s a name followed by a number.  The name is the name of the planet’s sun.  Our Sun is Sol.  The number is found by counting the planets out from the sun.  So Mercury is Sol 01.  Venus is Sol 02.  Earth is Sol 03.  The 0 is not really needed.  The official name of Earth is Sol 3. Local Federation headquarters is on the fourth planet out from the sun, Yband. That planet’s official name is Yband 4.
