The Sunnar System is a collection of orbiting celestial bodies that are gravitionally bound to the Sun. The Sunnar System began its formation 4.6 Billion years ago as a result of the gravitational collapse of a large interstellar molecular cloud. The vast majority of the Sunnar System's mass is found within its star the Sun (99.80%), with the majority of remaining matter situated in the two gas giants of Satre and Diaphres. There are 12 to 14 planets in the Sunnar System, with the status of Paidios and Pluta as either major planets or minor planets disputed within the scientific community[1].
The seven sunward planets - Hyperion, Balder, Eurth, Laran, Maraz, Petrus, and Andreus - and the three outer planets - Paidios, Pluta, and Vanth - are terrestrial planets composed of rock, metals, and ices. The four gaseous planets are significantly larger and more massive than the terrestrial planets possessing the overwhelming majority of Sun-orbiting matter, primarily made up of gaseous elements and molecules. All inner terrestrial and gaseous planets have nearly circular orbits that lie on the ecliptic plane however the outer planets possess more eccentric orbits that intersect the ecliptic.
