Stellar Systems Sets

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.

SOLAR SYSTEM: ORION
Pin Details: 40mm, Gold metal with mid-raised metal constellation background, translucent enamel, screen print
Of course it makes perfect sense if your favorite system is our own Solar System! Our sun is not part of a constellation, so the background of this design is the constellation Orion. I chose Orion for this design as our system is located in the Orion Arm of the Milky Way Galaxy. The Orion constellation has 5 significant stars in this arm with us: Betelguse, Rigel, and the three stars of Orion's Belt.

TRAPPIST-1 SYSTEM: AQUARIUS
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.

TOI-178 SYSTEM: SCULPTOR
Pin Details: 40mm, Silver metal with mid-raised metal constellation background, translucent enamel, screen print, cutouts
This system is 205 light years away, which is fairly close to ours. This implies that systems like it might be relatively common, and will help us gather information about planet formation and evolution. The planets in this system have varied densities, just as planets in our Solar System do. Unlike our system, TOI-178 doesn't have rocky inner planets and gaseous outer planets, the densities vary regardless of proximity to the star.

WOLF-1061 SYSTEM: OPHIUCHUS
Pin Details: 40mm, Silver metal with mid-raised metal constellation background, translucent enamel, screen print
Wolf-1061 is named after Max Wolf, German astronomer who first cataloged the star. In 2015 the discovery of the exoplanets were announced, a process of analyzing 10 years of HARPS spectrograph observations. This system is a mere 14 light-years away and planets in the system are likely to all be rocky. The second planet from its star is in the Habitable Zone, and the third planet is a super-earth located just inside the zone.

KEPLER-62 SYSTEM: LYRA
Pin Details: 40mm, Silver metal with mid-raised metal constellation background, translucent enamel, screen print, cutouts
There are two planets in this system within the Habitable Zone, both are categorized as super-earths. This system contains a planet with the mass of 36 EARTHS! The star is slightly older than our sun (4.6 billion years old), at 7 billion years old. The star is only 2/3 the size of our Sun, and 1/5 as bright. Unfortunately, the star is too dim to be seen from earth with the naked eye, it's apparent magnitude is only 13.75.

HR-8799 SYSTEM: PEGASUS
Pin Details: 40mm, Silver metal with mid-raised metal constellation background, translucent enamel, screen print, cutouts
HR-8799 is a young system, approximately 60 million years old, located in the Pegasus constellation. There are four planets in this system, and they are nearly all the same size! HR-8799e is nearest planet to the star and it has a radius of 1.17 Jupiters. The other three planets all have a radius of 1.2 Jupiters. Though none of the planets are within the Habitable Zone, HR-8799c is confirmed to have water in its atmosphere. In addition to the strange planets, the star of this system is also unique. The star is a Lambda Boötis star, meaning it has an unusual lack of metals in its surface layers.

KEPLER-90 SYSTEM: DRACO
Pin Details: 40mm, Silver metal with mid-raised metal constellation background, translucent enamel, screen print
Another system with eight planets other than ours? Yes, Kepler-90 not only has a star comparable to our Sun, but also rocky planets comparable to Earth! In fact, Kepler-90 was the second discovered eight planet system in history! All eight planets in the Kepler-90 system fit into the space equivalent from our Sun to Earth. The inner planets of this system orbit so closely to their star, Kepler-90i has a "year" of just over 14 days. The Kepler-90 name comes from Kepler, the mission that discovered the system originally, and 90 being the cataloged star number. Kepler-90 is located in the Draco constellation, and is visible with a medium-sized telescope.

V-1298 SYSTEM: TAURUS
Pin Details: 45mm, Silver metal with mid-raised metal constellation background, translucent enamel, screen print, cutouts
Most of the observed stars in this cloud are still forming protoplanetary disks, and very few have formed planets yet. V-1298 Tauri is a T Tauri Star (TTS), these stars are only tens of millions of years old. As this system is still developing, the planets vary greatly based on their distance from the star. The star is emitting so much x-ray radiation, atmospheres and oceans would have been stripped from the innermost planets in this system. The outermost planet is a gas giant, though the third planet from the star remains a mystery.

HD-108236 SYSTEM: CENTAURUS
Pin Details: 40mm, Silver metal with mid-raised metal constellation background, translucent enamel, screen print, cutouts
This system is 210 light years away from our Solar System and contains five exoplanets. Planets in this system have a close orbit to their star, too tight to fall within the Habitable Zone. Two planets are likely ice giants, while another two could be ocean worlds. HD-108236b is potentially a Super Earth; it could be a terrestrial or ocean world. The system's star is older than the sun and significantly lacks heavy metals, comparatively with only 50% the metallicity of the Solar System.

KEPLER-11 SYSTEM: CYGNUS
Pin Details: 40mm, Silver metal with mid-raised metal constellation background, translucent enamel, screen print, cutouts
This system has some similarities to our own, with a yellow star, rocky inner planet, and gas giant outer planets. This star is a yellow dwarf star located approximately 2,000 light-years from Earth. All planets in this system are larger than Earth, and were considered some of the smallest known exoplanets at the time of discovery. The inner five planets orbits could, comparatively, fit within the space between our Sun and Mercury, with the sixth planet orbit just outside the orbit of Venus.
