TRAPPIST-1: Aquarius

The designs in this series incorporate various representations for these systems:
Constellations: The constellation the system is located in, or associated with (Solar System), is mid-raised in the metal background of the design. Stars that are part of the perceived pattern in the constellation are represented by diamonds, while background stars are circles.
Stars: The largest metal circle in each design is to scale with the screen printed planets.
Planets: The order the planets are printed are innermost (top) to outermost (bottom). The metal circles also represent the planets, to a more clear scale, though they are not in any particular order.

Pin Details: 50mm, Silver metal with mid-raised metal constellation background, translucent enamel, screen print, cutouts
Named for the Transiting Planets and Planetesimals Small Telescope used to originally discover 3 planets in the system, Trappist-1 is the official name of the system's red star. Three of the seven confirmed planets are located within the Habitable Zone, and they are all earth-size. The exoplanets in this system are especially interesting, as it is possible any of them may have water on them. This makes the system a prime subject in our search for life outside of our own system.
