Every super-jovian has a Lagrange Point sixty degrees behind it in its orbit. As the planet orbits the star, the Lagrange Point orbits with it. As some systems may have multiple super-jovians, they will also have multiple Lagrange Points (LP).
These LPs act as mini-jump points within their system (single or multi-star). Because jumps from LPs are to destinations within the same system, the gravitational stresses are far less than for an interstellar jump point and therefore a ship does not require a Jump drive to use LPs, nor suffer from Jump shock. Any ship can make an intra-system jump from one LP to any other LP in the same system, even one orbiting a different star within the system. When you select an LP as a movement destination, you will get a list of possible intra-system jump destinations in the popup box where teams or commanders are selected.
A system will either have 2 or more LPs or none at all. They are shown on the map simply as LP1, LP2, etc. In the Task Groups window they are shown next to the planet whose orbit they share. So you might see Jupiter Lagrange Point as a destination. When you add intra-system jump orders, the name of the planet sharing the orbit is listed. So an order may read Intra-system jump to Jupiter Lagrange Point. Because these are intra-system rather than interstellar jumps, there is no scattering on arrival. As of v6.40, task groups will automatically assign themselves LP jumps when plotting a course.
