The four distinguishing characteristics of the spirals are: (a) they have more orderly, rotational motion than random motion (the rotation refers to the
disk as a whole and means that the star orbits are closely confined to a narrow range of angles and are fairly
circular); (b) they have some or a lot of gas and dust between the stars; (c) this means they can have new star formation occuring in the
disk, particularly in the spiral arms; and (d) they have a spiral structure.
