Astronomy of Qirsyllviar

The Astronomy of Qirsyllviar is as expansive as that of Earth. Besides several celestial objects observed with the naked eye every day and night, some things were long hidden until discovered by astronomers. Some things, however, can only be seen at certain times of the year or once every several years, decades or centuries.
== Qirsyllviar's Orbit ==
===Qirsyllviar's Moons===
Qirsyllviar has two moons, Erythrean (the red moon) and Galazios (the blue moon). The names of the moons were supposedly from a famous demon and deity respectfully, but whichever faith or pantheon the names came from has been lost to history. 
Erythrean's orbit is thirty-one days long, yet Galazios is the more further away of the two and so its orbit is about seventeen days longer than Erythrean's. It's rare to see them at full moon together, which happens at varying times and can last from one-to-four days on the rare occasion. It also due to the differing lengths of their orbits that the tides are less predictable.
On a rare occasion, Galazios will "catch up" to Erythrean and be eclipsed by its crimson twin.
Because of their unusual orbits, the moons partially eclipse the sun several times a year, but total solar eclipses are rarer than Earth's, and viewed roughly once every few hundred years.

=== Planets ===
Over the past several millennia, Qirsyllvian astronomers have observed several planets in the night sky. The observed planets are named for various mythological figures or deities based on how they are observed.

==== Harmonic Convergence ====
Harmonic Convergence is a period when all the planets converge into a straight syzygy that lasts for approximately three Qirsyllvian days. This astronomical alignment happens roughly once every three thousand years (give or take a few decades or a century), but the precise time is difficult to predict. The latest event was during the summer of 4542ᴀꜰᴢ.
=== Constellations & Stars ===
Several constellations and prominent stars have been created and named by various cultures over the past few thousand years. Most are named for various legendary or mythological figures or deities, or prominent creatures, based on how they are observed. Some constellations and stars have different names in different cultures, while others are known by a single name universally.

=== Saityroe's Comet ===
Saityroe's Comet is an orange, three-tailed, comet that that regularly passes by Qirsyllviar every 45 years, and is observed for approximately thirteen days. This celestial object was named for Saityroe Kadikache Loik Soynaltiar, a Maritymiri abjaksan from the Soynaltian Imperial Family, which coincidentally passed by at the time of his birth.
The comet has long been believed to be a source of pure magic, as every time it passes by, all magic users on Qirsyllviar have their powers increased one hundred fold. At the same time, the abjaksan also have their powers increased one hundred fold, just like they do during Harmonic Convergence.
The latest recorded passing of the comet was during the summer of 4542ᴀꜰᴢ.
=== The Sun ===
Qirsyllviar orbits an orange sun informally known by the names of various solar deities from various cultures.
== Notes & Trivia ==
* Qirsyllviar is the fourth planet from the son.
* Qirsyllviar is tiled on an axis at the like as Earth, and orbits the sun in an anticlockwise direction and rotates counterclockwise on its northern axis, and the northern axis points toward the north star at all times, but that's where the similarities end: Qirsyllviar's axis is less inclined than earths. What gives Qirsyllviar seasons equivalent to Earth's is the fact that its orbital eccentricity is greatly different from Earth's.
** Qirsyllviar's axial tilt is 17.25°, while Earth's is 23.4°; but like earth, Qirsyllviar's northern axis points toward the north star at all times.
** Qirsyllviar's orbital eccentricity is 0.075; Earth's is 0.017 (although those are the rough rounded numbers): 
*** So Qirsyllviar experiences the summer solstice at its Perihelion to its sun, when the north pole points toward the sun, while experiencing the winter solstice at its Aphelion, when the north pole points away from the sun.
**** Adding to this, Qirsyllviar's average velocity is 29.781km/s.
***** These numbers were generated using an orbital simulator site.
** With that in mind, all areas of Qirsyllviar experience the seasons roughly at the same time, despite minor differences in temperature from region to region, even though daylight doesn't all that much change much throughout the year.
** Also, even though Qirsyllviar's axis is less inclined then Earth, seasons on Qirsyllviar are roughly equivalent to what we experience on earth, hot summers, cold winters; but because the equator always receives more direct sunlight than the rest of the planet, all seasons felt in the regions around the equator are warmer. Regardless, because Qirsyllviar is closer to the sun during summer than winter, temperatures beyond the equator can still reach high levels.
** Qirsyllviar's year is also 7-8 days longer than Earth's, but leap years do not exist.
* Qirsyllviar's sun is an orange dwarf, a K-type main-sequence star to be precise:
** This type of star is not as hot as as Earth's, but it still emits enough heat to make Qirsyllviar habitable. 
* Since Qirsyllvian technology is too primitive, closer observation of all these astronomical bodies is extremely difficult; never mind exploration, which is impossible.
** However, the alien technology salvaged by Soynaltiar and Xotil allowed their respective astronomers to get a slightly better look.
* It is believed by Soynaltian astronomers that the craft that brought the technology they and the Xotil use came from one of the observed planets.
* Because the orbits of the Qirsyllviar's moons are different lengths, the eclipse cycle is even more irregular as Earth's.
