Jupiter is a white dwarf star instead of a gas giant. Jupiter's four main moons now orbit Saturn, Uranus, and Neptune. Due to the extra heating from Jupiter, Mars becomes habitable. The extra gravitational pull from Jupiter causes Venus to drift closer to the habitable zone in the early solar system, and becomes a tropical, life-bearing planet. Saturn, Uranus, and Neptune all become habitable; the asteroid belt, Kuiper belt, Oort cloud, and many a moon are either absorbed by a planet or star, or flung out of the system. Jupiter's orbit now takes it much further from the sun, completing a year in roughly two hundred Earth years, with the outer planets orbiting it instead of the sun.
