Armasta

Armasta
Armasta (actarian: World) was the fourth planet in the Armestis System located in the constellation Taurus on the edge of the Hyades Open Star Cluster. Armasta's density, radius and gravity were identical to Earth's. The average temperature of Armasta was slightly cooler than Earth by a measure of -1C. The planet boasted a range of ecological zones including deserts, forests, oceans, polar and alpine regions. The planet was orbited by two large moons, Suna and Busani, both of which orbited closer to the planet than Earth's own moon. The age of the planet and system were estimated to be approximately 4.5 billion years old, slightly younger than Sol. Armasta is one of two habitable planets in the Armestis system, the other being the third planet in the system, Kah.

Moons
Armasta is orbited by two large moons; Suna and Busani; both named after their counterparts in Sojxen Mythology. Suna and Busani have a radius of 1647km and 1055km and orbit Armasta at a distance of 178,300km and 86,600km respectively. Although Suna is larger, Busani appears larger in the Armastan sky because of it's closer proximity to the planet.

Both moons were believed to have been formed from a large glancing impact with Armasta by another proto-planet early in the star system's formation. Because of the relatively low mass of each moon, they both achieved a stable, circular orbit around the planet rather than merging. The composition of each moon is slightly different. Suna is mainly comprised of silicate rock while Busani has a higher abunance of Ferrous material in it's crust and mantle, owing to it's reddish-tan color. The surfaces of both moons are relatively young, leading geologists to believe that both moons are still tectonically active and undergo massive resurfacing events every 500 million years. The moons' interiors are heated by the gravitational interactions and tidal forces between each other and Armasta.
