Another important thing to remember for interstellar travel is that every star, or massive body, has a different Limit. The Limit around Sol is almost perfectly spherical, whereas the Limit around Alpha Centauri is more like a giant ameboa 30 AU by almost 90 AU across, or the Limit around a dwarf star like Proxima Centauri is only 5 AU. The Limit around a star like Rigel might be somewhere around 100 to 500 AU, and so it goes.
Hades Station exists to study the Limit, as its location at the Pluto-Charon L3 allows it to swing back and forth along the sphere's boundary.
The hypothetical conquest of Cochrane's Limit is known as a Limit Break.
- Including, quite literally, the phase of the moon
- Binary, trinary and more complicated stellar systems should be approached with caution.
