Spaceports

You may be looking for orbital spaceports.
== Introduction ==
Spaceports are structures located on planets that allow for landing and docking of spacecraft, like how seaports are for sea-craft and how airports are for aircraft. There are 17 major spaceports on the planet Earth. Though spaceports aren't just utilized by humans, they are found on planets like Sanghelios and Kepler-186f, along with other colonized planets.
