The class of starport will indicate whether the system also has an orbiting Spaceport or a Jump Station. A spaceport generally orbits the most densely populated planet of the system. A Jump Station is a type of spaceport, but is located within a day of a predefined Jump Point, which is usually several days travel from the most densely populated planet in the system.
Shipyards - The presence of shipyards means that spaceships and starships can be built.
Guest Facilities - Guest facilities includes hotels, restaurants and other amenities designed for the comfort of the crews and passengers of visiting ships.
