Via Elite-B; provide visible variation on the size of stars.
This yields a number of other related behaviours, such as:
Fuel scooping from stars varies by star size and type; larger stars yield better scooping but a safer distance is required
Planets are farther from bigger stars and closer to smaller stars
Where you drop into a system is dependant on the size of the star; larger stars have greater gravity and hyperspace will drop you off closer to them. Smaller stars will drop you off nearer the planet
Smaller ships are likely to overheat if they pursue you around the star too much
Thargoids cannot release Tharglets near the sun (they overheat quickly)
