Its magnetic field, 50 times stronger than it is today, helped the planet accumulate surrounding material. As the material dissipated, Jupiter began to contract under its own gravity. Its volume shrank and its rotation speed increased. Jupiter is still shrinking, albeit slowly, as both its surface and internal temperatures continue to drop.
