Kepler was a seventeenth century German astronomer and mathematician who developed laws of planetary motion that later helped Edmund Halley predict the return of the comet that now bears his name. These forms symbolize Johannes Kepler's fascination with geometric shapes to describe the universe. Two-foot tall dodecahedrons in star shapes represent the head of the comet. Note: Comets are basically frozen bodies of ices, dust and rock and usually do not begin to form comas and tails until they approach the Sun close enough for their ices to begin to vaporize.Įach sculpture sits on a black concrete slab embedded with glass stars and glittery silicon carbide. In September 2008 two Comet Halley sculptures were added to the Solar Walk (commissioned also by the City's Art in Public Places Trust, and designed by the artist Elizabeth Indianos with technical help from the AAC): (1) A Perihelion Sculpture with Tail at the location of the comet's closest point to the Sun between Mercury and Venus and (2) an Aphelion Sculpture without tail at the comet's farthest point from the Sun about halfway between Neptune and Pluto. Several enhancements have been made to the nearly-mile long attraction, including interpretive signs, "star benches", and two sculptures representing the Comet Halley's travels throughout the galaxy. The Solar Walk was first conceived in 1998 and construction finished in 2002. Each shows the planet's relative size compared to the Sun in this 4 billion to 1 scale, distance from the Sun, rotational and orbital period, a rubbing area for the Solar Walk "passport", and more. Information plaques adorn each planetary monument. These plaques are an inherent facet of the educational model. Realize the vastness of the Milky Way by taking a simple walk down 8th Avenue, or travel in light years and sprint through the universe. One of the most out-of-this-world jogs you'll ever take.
