The Ionious Solar System is located in the Arm of Orion in the Milky Way Galaxy. Ionious is composed of Hestia and five planets. Hestia is a class G star. This yellowish star is little bit hotter and brighter than our G 2 star. Hestia will have a life span of 9.18 billion earth years.

Our planet Vesta and four other planets orbit around Hestia. The innermost planet, Boreas, is small, rocky and too hot for any forms of life. The second innermost planet, Zephyrus, is a little larger than Boreas, but again too hot and rocky to allow any form of life. Further out from Hestia, there is a life zone where Vesta and Notus orbit. Vesta is a perfect planet which has an atmosphere and water. Notus is in a life zone, but covered with rocks. We expect that some kind of life exists there, but this planet has not yet been explored. Eurus is the outermost planet, but is the largest planet in the system, and has no sign of any life form.

Boreas is the nearest planet to Hestia. Also, it is the smallest planet in the Ionious Solar system. The distance of Boreas from the sun, Hestia is 0.33 AU (Astronomical Units) and it takes Boreas 0.19 earth years (Approximately 69 earth days) to orbit Hestia. Boreas' structure is composed of the core, mantle, and crust. The outer part is called crust, the medium part is called the mantle, and the inner part is called the core. This structure mainly made of silicate rocks. The surface of Boreas is covered with dust, rocks, and boulders and is being heavily cratered by meteor showers that strike the surface of Boreas. There is no atmosphere.

Zephyrus is the second planet that is next to Boreas. The distance of Zephyrus from the sun, Hestia is 0.66 AU (Astronomical Units) and it takes Zephyrus 0.66 earth years (Approximately 241 earth days) to orbit Hestia. Zephyrus's structure consists of core, mantle, and crust too. Crust and mantle are made of granite rocks, but the core is made of solid iron metal. Zephyrus is denser than Boreas. The surface of Zephyrus is mostly covered with rocks and dust like Boreas, but less cratered.

Zephyrus has an atmosphere that is mainly filled with carbon dioxide. The temperature on the surface is a lot hotter than Boreas. These conditions make the existence of any terrestrial life almost impossible.

Vesta is the third planet from Hestia. The distance of Vesta from the sun, Hestia is 0.97 AU (Astronomical Units) and it takes Vesta 0.96 earth years (Approximately 354 earth days) to orbit Hestia. Vesta is a planet containing plenty of waters on the surface and a good atmosphere that absorbs the energy from the Sun. Vesta's atmosphere recycles water and other chemicals and sustains moderate climates that are suitable for a wide variety of life forms and bio zones.

Vesta has several large tectonic plates that form the surface of the planet. The locations where the plates' collisions or subductions occur are called hot spots. In the hot spots, many active volcanoes exist and they shoot out hot magmas on the surface. This hot magma became the rocky continental crust and it permits unique and varied land formations. Accompanied by volcanic explosions, extremely dangerous earthquakes are generated occasionally. Although Hestia is little bit warmer than the sun in the Solar system, temperatures on planet Vesta are very similar to those of Earth because it is located 0.97 AU from Hestia. Vesta has five major climate zones: tropical, tepid, temperate, glacial, and polar. Vesta is made up of approximately 80% water and 20% land. A moon called Jocasta rotates around planet Vesta.

Notus is the fourth planet from the Sun, Hestia and it is a sister planet of Vesta. The distance of Notus from the sun, Hestia is 1.23 AU (Astronomical Units) and it takes Notus 1.35 earth years (Approximately 493 earth days) to orbit Hestia. Notus 's structure is composed of core, mantle, and crust too. This structure is mainly made of granite rocks. The surface of Notus is mostly covered with rocks and dusts like other planets. The atmosphere of Notus is quite different from that of Vesta. It is composed primarily of carbon dioxide with small amounts of other gases. Notus is a little bigger and denser than Vesta. There is no sign of terrestrial life forms.

Enrus is the outermost planet from Hestia and it is the largest one in the Ionious Solar System. The distance of Enrus from the sun, Hestia is 3.28 AU (Astronomical Units) and it takes Enrus 1.35 earth years (Approximately 1197 earth days) to orbit Hestia. It is entirely made of gases. Enrus is believed to be in the early stage of planet formation. The solid surface has not been formed yet. The temperature of this planet is extremely cold both day and night due to the long distance from Hestia. The heat of the sun barely reaches to Enrus.
