Reunion-Centric Solar System

Texas has a unique opporitunity for a scientifically educational art installation along its I‑35E/I‑35 corridor from Dallas to Laredo. Using the globe on top of Reunion Tower in Dallas as a 'Sun' for both position and scale, the project would install a road sign for each planet the appropriate distance from the tower, with a picture of the planet, its name, and its distance from the Sun in Astronomical Units (AU).

The project need not be affiliated with Reunion Tower in any way. The tower is referenced only to establish the scale, approximately 0.0000000258491, and as the origin from which to measure all distances.

Each planet would get a road sign. The position of the sign along I‑35E/I‑35 would be determined by applying this scale to the minimum and maximum orbital radius of the planet, and measuring south from the tower. For example, Earth's orbit at this scale would place it 2.363 to 2.443 miles from the tower. Therefore, Earth's road sign would be on I‑35E approximately at the South Marsalis Avenue bridge (near the Dallas Zoo). The road sign would have a pictorial representation of the Earth at this same scale, just over 1 foot in diameter. Below the picture would be the words "Earth     1 AU" in guide-sign format.

Each planet would get a similar sign. The size of each sign would vary depending on the size of the planet and/or lettering requirements. The Earth's sign is the smallest at 13 x 14.5 feet in size (most are near this size), and Saturn's is largest at 23 x 21 feet.

There are several stretch goals for this art project:

Texas is uniquely suited to this project based on several factors:
