► Alspher System
Alspher System is a binary star system located 1054 light years from the solar system. Being nurtured by the lights of the two parent stars, the planets and moons of Alspher System is full of vibrant life, exotic landscape and many secrets. This system is highly detailed and it took me a huge amount of time. Hope all of you will like it.

Some of the highlights of the system

Alspher System is a binary system, consisting of an F-type main sequence star and an M-type main sequence star.
Alspher I is an F-type main sequence star, containing a whopping total of 24 planets, at which 18 are major planets (8 terrestrial planets, 4 ice giants and 6 gas giants), and 6 are considered dwarf planets.
Kameni is the first planet of Alspher I. It is a gas giant with the lowest density of all celestial bodies in the system. Due to the extreme thermal heating from the star, the planet is extremely inflated, giving its name as a "puffy planet". Moreover, the immense solar winds form Alspher I is also slowly stripping away the planet's atmosphere, resulting in the planet with a "comet-like" appearance.
Kolasi is the 2nd planet and major planet of Alspher I. It has the highest temperature among all major planets.
Varys is the 5th planet and major planet of Alspher I. It is a massive hot desert with a thick atmosphere and 1 major moon.
Ydaris is the 6th planet and major planet of Alspher I. It is a hot oceania with 3 major moons.
Pelorios is the 9th planet and 7th major planet of Alspher I. This super-jupiter is located comfortably in the habitable zone, aiding the emergence of multicellular aerial life due to its water vapour in the atmosphere (that also gives the planet a bluish-white colour). Being the most massive and largest planet in the system, it is surely a sight to behold.
Pelorios also has the most impressive rings in the entire Alspher System
Pelorios has a total of 16 major moons, making it to have the largest number of major moons in the system. The extensive moon system is also evident from the picture below
Ethroda is the innermost major moon orbiting Pelorios. It orbits within the largest gap in its parent planet's rings.

Zoi is the 2nd major moon of Pelorios. This terra moon has a general tropical climate, harbouring rich multicellular life.

Kyro is the 3rd major moon from Pelorios. It is super-earth sized terra moon that contains lifeforms that are panspermiated from Zoi. It is also interesting to note that Kyro has its own rings.

Zoiros is the 5th major moon from Pelorios. Despite its terra status, it doesn't have life on it.
Romi Ardar is the 8th major moon from Pelorios. It is a cool oceania.

Aeriodia is the 14th major moon of Pelorios. It is an ice giant moon with a long orbital period of over 200 days. Being massive and so far our from its parent planet, the moon is able to have its own 2 major moons (that can be called "grand moons" or "moons moons"). Similar to Kyro, Aeriodia is one of the few moons that has its own ring system.
Doxa is the 11th planet and 8th major planet of Alspher I. It is a gas giant with 1.8 jovian masses and a highly tilted rotational axis. It has 10 major moons.
Fhex is the innermost major moon of Doxa. Despite the fact that Doxa is far out of the habitable zone, liquid water is able to exist on Fhex due to the gas giant's tidal heating.
Synnefo-Bhukann is a double ice giant system. It is the 12th planet and 9th major planet of Alspher I. It contains 2 major bodies and numerous smaller moons. 4 major moons orbit the system barycentre in P-type orbits.
Synnefo is the largest body in the Synnefo-Bhukann system. It is an ice giant with 2 major moons with S-type orbits.
Bhukann has a slightly smaller mass than Synnefo, making ti technically the most massive and largest moon in Alspher System. The moon has 2 major moons orbiting around it with S-type orbits.

Vronti is the 13th planet and 10th major planet of Alspher I. It is a bluish gas giant with 5 major moons.
Idathis is the innermost moon of Vronti. It contains unicellular subglacial life.
Chnoudi is the 14th planet and 11th major planet of Alspher I. Due to its relatively low mass and hydrogen-rich atmosphere, it is considered a "gas-dwarf". In fact, it is less massive than the most massive terrestrial planet in the system (Omichlodis).
Omichlodis is 15th planet and 12th major planet of Alspher I. It is a massive titan with the thickest atmosphere among all non-gaseous planets in the system.
Oxaron is the 3rd major moon of Omichlodis. It in essence is a titan moon around a titan planet.
Pagoma is the 16th planet and 13th major planet of Alspher I. It is a white gas giant with 11 major moons.
Skotadi is the 18th planet and 15th major planet of Alspher I. It is a small frozen desert with the slowest rotation among all the planets.
Phuran is the 19th planet and 16th major planet of Alspher I. It is an ice giant.

Teras is the 20th planet and 17th major planet of Alspher I. It is a super jupiter with over 4 jovian masses and 13 major moons.
Ebesol is the 4th major moon of Teras. It is a titan.
Yrucrem has the largest semi-major axis among all major moons in the Alspher system. Due to the Teras' far distance from the parent star and its high mass, the planet's extensive hill sphere makes such an orbit stable. It is also important to note that Yrucrem is one of the few major moons that are not tidally locked to their planets.
Taxidodis-Caaran is the 22nd planet and 5th dwarf planet of Alspher I. It is binary dwarf planet system. Taxidodis is the major body in this system.
Proorismos is the 23rd planet and 6th dwarf planet of Alspher I. Due to its extremely rapid spin, the dwarf planet is the most oblate object in Alspher system. In this picture, its innermost major moon, Hesdis, can also be seen.
Akro is the farthermost planet and major planet of Alspher I. Its unique origin of being captured by the star explains its eccentric, highly inclined and retrograde orbit. One year of the ice giant is equivalent to over 43000 Earth years.

Alspher II is an M-type main sequence star, containing a total of 20 planets, at which 13 are major planets (8 terrestrial planets, 2 ice giants and 3 gas giants), and 7 are considered dwarf planets.
Agonos is the innermost planet of Alspher II. Due to the high inclination and eccentricity of its orbit, the planet has a spin-orbit resonance of 5:2 instead of the usual 1:1. The small scorched desert is also highly oblate due to its extremely rapid spin.

Evyssos is the 2nd planet and major planet of Alspher II. Similar to Agonos, it also has an unusual spin-orbit resonance (2:1).
Ti’Evvor is the 3rd planet and major planet of Alspher II. It is a warm terra with an exceptionally complex atmosphere.
Tempestas is the 4th planet and major planet of Alspher II. It is a red ice giant with 3 major moons.
Caeruleum-Daphix is a binary planet system. The major body, Caeruleum, is the 5th planet and major planet of Alspher II. 3 major moons orbit the system barycentre in P-type orbits.
Caeruleum is a massive terra with organic unicellular life.

Daphix is a large desert that also bears organic unicellular life.
Densissima is the 8th planet and 6th major planet of Alspher II. It is a gigantic titan. What makes it so special is the fact that it harbours both organic multicellular and exotic multicellular life.
Suirus is the innermost major moon of Densissima. It is a large selena moon with an unusually thick atmosphere.
Diphula is the 9th planet and 7th major planet of Alspher II. It is a very massive desert planet, with the highest density among all planets (10.972g/cm^3) and a very thick atmosphere.
Tyfario is the 10th planet and 8th major planet of Alspher II. With over 2.2 jovian masses, it is the most massive planet of Alspher II.
Anhough is the 3rd major moon of Tyfario. It is a large titan moon.
Ulonte is the 11th planet and 9th major planet of Alspher II. It is a frozen selena with a chlorine atmosphere.

Iorides is the 12th planet and 10th major planet of Alspher II. It is a gas giant with a highly unusual appearance. The pink colour in its atmosphere has resulted from the exotic multicellular life it contains.
Bhuurt is the 13th planet and 11th major planet of Alspher II. There are exotic unicellular subglacial residing on ice world. Another interesting thing to mentioned is that Bhuurt has a retrograde rotation, likely resulted from an ancient collision.
Lipos is the 15th planet and 13th major planet of Alspher II. It is the furthermost major planet orbiting the star. Due to its rapid rotation, Lipos has an unusually oblate appearance. Due to the inadequacy of sunlight from Alspher II, the following picture of Lipos taken under ambient lighting to show its true colours.

Isreenda is the 20th planet and 7th dwarf planet of Alspher II. It is the planet with the largest semi-major axis orbiting Alspher II. A year on Isreena takes over 41000 years, comparable to that of Akro.
