Wussy star. It's the joke of its galaxy now.
It's not really that different that what Jupiter has with Io.
As I recall Jupiter puts out more energy than it recieves from the sun - so Jupiter and its moons resemble a star system.
Most star systems out there are binary systems (have two suns) Jupiter was to be our "second sun" but it was apparently too small to initiate fusion.
