am'nýer—a'
T
Tam'nýer—a''s solar system is quite complex and stark at the same time. While the system is large it is spread out containing little. The thing that makes this system interesting though is that it only contains 3 planets, 16 moons and yet has two suns.
Basing it off of our solar system, let's imagine for a moment that Tam'nýer—a', which has a right axis tilt, would be represented by Earth, and its main sun would be the same distance as our solar system's main sun, which is 149.6 million kilometers (92.96 million miles). However, Tam'nýer—a''s main sun is about 10% less in mass. To be clear, Tam'nýer—a''s main sun is classified as a Red Dwarf star, where as Earths sun is a Yellow Dwarf. Earth's sun temperature is 5, 778K (9, 940.73 °F), and Tam'nýer—a''s, being a Red Dwarf, is at most 4, 000K (6, 740.33 °F). This indicates that Tam'nýer—a' would be a rather cool planet, perhaps too cool to host life, if not for its second sun.
Now Tam'nýer—a' does also have a moon, called Nue, but is closer than ours. Tam'nýer—a' being a predominantly water based planet, like the Earth but with more volume, the tides are more extreme. So, let's break this down as well. Earth's distance to the moon is 384, 400 kilometers (233, 855 miles). For Tam'nýer—a' and its moon (Nue), the distance is about 80 kilometers less, so let's round to 300, 000 kilometers away. It may not sound like much, but for our space travel technology that we have right now here on Earth, that essentially cuts it down to 3 days to travel to the moon from 4. This subsequently makes the low and high tides significantly more extreme.
The highest tidal change here on Earth is at the Bay of Fundy which separates the provinces Nova Scotia and New Brunswick in Canada. The tidal change is 16.3 meters (53.47 feet). Now while this only really happens in the Bay of Fundy, this is the average for all of Tam'nýer—a'. The highest tidal change on Tam'nýer—a' is a whopping 24.7 meters (81.04 feet) and it happens at the most eastern of the Ãoni Coast islands. This most likely explains the greater amounts of erosion that can be seen there as well.
With this, we haven't even touched the system's second sun. To give you an idea of the distance between this second sun and Tam'nýer—a', imagine the distance between Earth and Saturn. It's a distance of 1.2 billion kilometers (746 million miles) or 8 times the distance between Earth and the sun. So, Tam'nýer—a''s second sun is relatively far away, and more akin to having two full moons at night, except this second sun would be 50x brighter than a regular full moon. This means that Tam'nýer—a' is never pitch black, but the stars are still visible at night, just fainter than we are used to. Which makes seafairing much more interesting as rather than following the north star, you'd be following the second sun.
Due to Tam'nýer—a' having two suns comes in the duration of a year. With Tam'nýer—a''s orbit, over the period of thousands to millions of years, her orbit has gone through many changes, but for the moment the planet orbits both suns. Once the orbit of the first sun comes to it's climax Tam'nýer—a' gains acceleration, being slingshot to break orbit with the first and make way to fall in line with the second sun. Essentially, Tam'nýer—a' is making an expansive and heavily lopsided infinity symbol orbiting both suns. This long travel makes Tam'nýer—a''s annual duration somewhere in the range of 11,000 days.
OTHER PLANETS
Ḍu-thāçi, The Largest Planet:
Right next to the second sun is the largest planet in Tam'nýer—a''s system, Ḍu-thāçi (g-duh-taah-see). 1.5 times the size of Jupiter, it is on equal standing in size to the second sun, but of course, due to its proximity to the second sun, it is much too hot to host life. It does, however, host 15 of the 16 moons in the system, as though the second sun and the planet have a mobile to entertain them. For the mere sake of mentioning, 4 of Ḍu-thāçi's moons are in hydrostatic equilibrium (symmetrically rounded into a spheroid shape due to gravity), this is because of the proximity of the second sun, and their mass. Ḍu-thāçi is the brightest star in Tam'nýer—a''s sky, apart from its two suns, and can still be seen through the array of colours during the aurora borealis. It should be mentioned, however, that Ḍu-thāçi is only visible for half the year, due to Tam'nýer—a''s orbit.
Cweks, The Loner Planet:
Far off from Tam'nýer—a' and Ḍu-thāçi, seemingly on its own and only gaining heat and light from the main sun is the last and third planet of Tam'nýer—a''s star system, Cweks (suh-weh-k-s). Cweks is much different than Tam'nýer—a''s or Ḍu-thāçi as it is very dark in the sky. This is most likely due to it being a carbon planet, which also makes it cold, and devoid of oxygen. While very dark on the surface, as the carbon here is more akin to the graphite of your pencil, underneath the crust of it is kilometers upon kilometers of solid diamond. Cweks is a planet that truly represents 'don't judge a book by its cover'.
