| Cronox System | Cronox System Planets of the Cronox-Cordes system Terrestrial planets of Cordes, to scale Position of Cronox in Syndicate space Cronox [CRON-ox] is a S-type detached-binary star system consisting of the stars 1GD.Pa-Cordes and 1GD.Pb-Arjos. The two orbit a common barycenter at a sufficient distance for each to have its own independent planetary system. The two stars' orbital planes are at 83 degree angle from each other, which suggests that the two stars originally formed independently o… |
| Daystar | Daystar The daystar, also called the Son, is a bright star visible in both the day and night skies of northern Helevos, depending on latitude and time of year. The star appears to hang in the night sky near the north pole, so that on the equator it is only sometimes visible, and becomes completely invisible further south. |
| Fixed stars | Fixed stars The Fixed Stars are the bright stars, more properly small moons, in the sky of Helevos. They are so called because they hold a fixed point in the night sky relative to the ground. There are thought to be four fixed stars, circling the heavens at the four quarters of the globe. Only three are visible in the skies of the |
| Helevos | Helevos Helevos (also known as Vos, or Veeos) is a temperate terrestrial world, fourth planet of the star Cordes in the Cronox binary star system. The stars Cordes and Arjos are distant binaries, so on Helevos, Arjos is only seen in the northern hemisphere as star, sometimes bright enough to be seen during the day, circling roughly over the viridgreenAnásthiasAnásthiasAnásthiasgreen |
| Moons | Moons Helevos has two moons: Thea, a pink-white disc which passes through phases in the night sky, and Themsa, a bright discus-like moon that spins quickly through the night sky. Thea Thea is the larger moon, a disc about half the size of Earth's moon, and much less bright. It's surface coloration varies from grey to red ochre, giving Thea a pinkish light in the night sky. |
| Official Naming Convention | Official Naming Convention Official Naming Conventions are common interstellar agreements about the naming of stars, systems and planets. Planetary names in particular can be highly politicised, because long-established worlds may have a variety of local names used by different groups or nations, names applied to them by other planets in the same system, and yet other names applied by cultures in distant systems or by colonial powers. |
| Thea | Thea Thea, or Theeya, is the larger of the two moons of Helevos, the smaller moon being Themsa. Thea is a spheroid approximately 1582 km in diameter. I's surface is covered with an ochre iron-silicate dust with mountain ranges of lighter grey rock. In the night sky it appears as a disc less than half the size of Earth's moon, and much less bright. It's surface gives Thea a pinkish light in the night sky. |
| Yending Meridian | Yending Meridian The Yending Meridian is the prime meridian for measuring longitude on Helevos. The line is relative to the fixed star, Yendimzar. This star hangs directly above the equator, geosynchronous with a point in eastern Harthera. In the mythology of Anrel and Miyarris, Yendim was the first and greatest city of the |
