Single star systems like our solar system are in fact not the most abundant in our universe. This research paper will specifically investigate the wide, or visual, binary star systems within the Hyades open star cluster and their positions on color-magnitude diagrams (CMD). To do this, this work incorporates the Gaia EDR3 dataset and python coding to conduct the mass selection and graphing of the data. The stars within the Hyades are first selected by evaluating their coordinates and then their relative motion. This maximizes our accuracy in selecting gravitationally bound stars within the Hyades. Then, by further reducing the margins, this paper identifies comoving wide binary star systems within our initially selected Hyades candidates. Finally, the CMD of the wide binary star systems within the Hyades star cluster is plotted along with the other none-binary star systems within the star cluster and the stars within the local 100 parsec (pc) of the Earth.
