Population I stars are young stars that formed relatively recently from interstellar gas and dust. They are generally found in the disk of the galaxy, and their orbits are mostly circular and confined to the disk. This is because the disk is where the interstellar gas and dust is most concentrated, and where star formation is most active. Population I stars have not had enough time to be gravitationally influenced by other galaxies or dark matter, so their orbits are relatively stable and circular.
