    Simple - Jupiter lacks the mass to maintain a self sustaining fusion reaction. Its what we would call a sub sun in many respects - it simply lacks the gravitational mass to create the reaction needed to become a star/sun on its own.

    Despite that, it is the only planet that generates its own heat, because of gravitational tides and internal convection.

    Darn'd good question.

    Its because Jupiter isnt big enough to become a star.

    Dude, I know what road youre goin down. I had a question like yours before.

    It was not quite large enough for the gravity to ennable the strong force to come into play. This happens through intense gravity and heat, and causes fusion.

    The strong force only works when particles are extremely close, and when electrostatic forces are overcome.

    MINUS 167 degrees! You forgot the negative sign.

    Even if it was +167, that's cooler than Mercury. The sun's surface, its coolest layer, is 5500 K.
