Halteres, a conjoined binary terrestrial system, consists of a larger lobe, Halteres Major (H-Major), a smaller lobe, Halteres Minor (H-Minor), and a shaft of igneous rock connecting the two, the Pillar of Cael (Cael).
As a result of their bond, an uninhabitable volcanic wasteland called the Foculus covers the medial 25% of both attached lobes surrounding Cael.
Halteres is the second planet from Hestia, a K-type dwarf star. Hestia’s solar system contains six planets, from nearest to farthest; Vélkáf, Halteres, Clach Nearth, Kovoldia, Sfyri, and Akontio.
The solar system lies in one of spiral arms of the Glyptis galaxy, approximately three-quarters of the way out from the center of the galaxy. Glyptis, a spiral starburst galaxy, resides near the farthest edge of the Fovero galaxy cluster. The Fovero galaxy cluster is near the center of the Sympan supercluster.
These deep space objects sprawl over 2 billion light years from Earth with approximate Earth celestial coordinates right ascension 19h 46m 25.66s and declination +33° 43′ 40.02″.
Orbit and Rotation
Halteres orbits Hestia in 208.45 Earth days. During this time, it rotates about its axis about 100.06 times.
H-Minor displays perpendicular rotation, three times for each planar rotation of the system, much like a millstone.
Furthermore, stabilized by the presence of H-Minor, the planet’s axis of rotation aligns with its orbital plane.
According to unverified evidence, the planet formed over 4.6 billion years ago. It possesses no natural satellites, though H-Minor is thought to have been formed from a collision, but unlike the Earth’s moon, didn’t separate. Similar to the moon, H-Minor causes perpetual tides around the polar circumference of H-Major.
The lithosphere on H-Major divides into several rigid tectonic plates. Over many millions of years, they migrated toward the equatorial plane.
Water covers about 62% of H-Major’s habitable surface, mostly by oceans. The remaining 38% consists of continents and islands that together contain many lakes, rivers and other sources of water that contribute to the hydrosphere. Ice covers the majority of H-Major’s polar regions. Additionally, certain sections of the polar ice caps, called the Pagos Nefos, rotate over the Foculus, become infused with steam, and float inland.
100% of H-Minor’s surface is land.
Compared to Earth’s 5.51 g/cm3, H-Major’s density is 3.89 g/cm3, while H- Minor’s is 17.34 g/cm3.
H-Major’s interior remains active with a solid iron inner core, a liquid outer core that generates a magnetic field, and a convecting mantle that drives plate tectonics and makes the Foculus unstable.
Other than a large hollow portion, Vathoul, which has been artificially excavated, H-Minor’s interior is solid throughout. Subsequently, H-Minor has no magnetic field.
According to unverified evidence, life arose in H-Major’s oceans as early as 4.1 billion years ago and began to affect its atmosphere and surface, leading to the proliferation of anaerobic and, later, aerobic organisms. Since then, the combination of the planet’s distance from Hestia, H-Major’s physical properties, and geological history have allowed life to evolve and thrive.
Life evolved similar to Earth’s. However, three known sapient subspecies inhabit H-Major; the Haltierre, Ratnik, and Mendax, who now inhabit H-Minor. Unverified evidence exists of a sentient arachnid species, the Noctvyl. Additionally, the Astir Espera region of H-Major harbors the only in situ population of the omniscent organic circuitry Arca Trochia.
