Colored-coded tiles imbedded in the side of the Jupiter column and on the plaza in front of the column enable a person of any height to find the optimum location to stand and observe Polaris (North Star), a critical point in the sky when learning about the Earth's motion. The tile color that is at a person's eye level determines the color of the plaza tile on which that person should stand in order to see Polaris through the center of the circle of the steel sculpture atop the column The columns to the east and west are aligned with the spring and autumn equinoxes,
and columns adjacent to those line up with the solstices. Each column is topped with
an iron sculpture, some decorative and some for celestial functionality. The sculpture
atop the Jupiter column has a circle set in the center of a set of radial lines with
15° separation. These lines are used to measure the time of passage of a given star
between two contiguous radial lines in an experiment to determine the length of the
day. In addition, we have included features in the concrete of the plaza that, with
the shadow of the gnomon atop the Sun column, serve as a solar clock that is large
enough that an entire science class can stand on.
