It is known that gas giants around other stars are often located very near their sun. According to accepted theory, these gas planets were formed far away and subsequently migrated to an orbit closer to the star. Now, researchers from Lund University and other institutions have used advanced computer simulations to learn more about Jupiter's journey through our own solar system approximately 4.5 billion years ago. At that time, Jupiter was quite recently formed, as were the other planets in the solar system. The planets were gradually built up by cosmic dust, which circled around our young sun in a disk of gas and particles. Jupiter was no larger than our own planet.
