Your home planet, sometimes known as your "homeworld" or "home world", is the planet that you start with. All players in most universes (all English, Polish, Argentinian and from other countries) start with 163 fields on their home planet. However, in some of the early German universes the home planet had 7 fields. Home planets can be deleted if you are in Juro universe.
Many players don't change the original name "Homeworld".
