A colonist is a sophont being who leaves eir homeworld to colonize a new solar system. Even in the current era, finding and colonizing a new and uninhabited world or solar system is not an easy matter. Almost always, someone will have gotten there first (usually isolationist ai, autonomous neumanns, etc.). Most colonization projects are sponsored by developmental corporations, large polities, or empires, which have already created the infrastructure on the new world. There is usually a limited quota on inhabitants, and until a wormhole or beamrider relay is set up, transport can be difficult. Most colonists conform to the preferred memotype of the polity that is developing the new solar system.
Colony - Text by M. Alan Kazlev Dependent member of a larger polity or empire. It is ruled by the parent polity, usually through a governor or colonial administration AI. The colonists may have an elected council to petition the governor, or an elected or chosen representative in the parent polity or empire, but they have no say in their own government. Colonies may be established as part of an expansionist drive by the parent polity or empire, or they may be regions that already have a society but were technological inferior and hence easily conquered. Colonies tend to be less organized and with less government (less infrastructure, luxury items, no welfare services or angelnets, etc.) than the parent polity. See also territory, protectorate.
Landing Day - Text by Todd Drashner A popular holiday among the baseline/near baselines of many systems. This is the day that their colonization venture first arrived on the planet or in the system they inhabit. Naturally it is a different day for every system.
