A representation of the star and all the planets in the solar system to scale by their sizes, each with their name in Circular Gallifreyan written across the surface.
A depiction of the incredible newly discovered TRAPPIST-1 exoplanet system, with SEVEN earth-sized planets! In Circular Gallifreyan, the star says "TRAPPIST 1," and the star and all the planets (although they're difficult to see here as they are to scale) have the letters a to h on them also in Gallifreyan.
The objects on the newly-discovered TRAPPIST-1 system in relative scale with one another. Each object has its letter designation in Circular Gallifreyan as well, from a to h.
