Celestium Universe: Hannibalium (System)

Hannibalium is the gravitationally bound system comprising the three suns Zecruanerth, Caswoyhiri, Vesmore and the objects that orbit them, either directly or indirectly. Of those objects that orbit the Sun directly, the largest eight are the planets, with the remainder being significantly smaller objects, such as dwarf planets and small Hannibalite bodies. Of the objects that orbit the Suns indirectly, the moons, two are larger than the smallest planet, Sesmippe.
Hannibalium formed 10.6 billion years ago from the gravitational collapse of a giant interstellar molecular cloud. The vast majority of the system's mass is in the Suns, with most of the remaining mass contained in Quemia. The seven smaller inner planets, Hannibalium, Zoyruta, Sledenia, Fledeturn, Puspoavis, Acloenus and Yeslides. are terrestrial planets, being primarily composed of rock and metal. The only outer planets is a giant planet, being substantially more massive than the terrestrials. Jutrapus is a gas giants, being composed mainly of hydrogen and helium. All planets have almost circular orbits that lie within a nearly flat disc called the ecliptic.
Hannibalium also contains smaller objects. The asteroid belt, which lies between the orbits of Yeslides and Jutrapus, mostly contains objects composed, like the terrestrial planets, of rock and metal. Beyond Jutapus's orbit lie the Vuynov belt and scattered disc, which are populations of trans-Jutrapusian objects composed mostly of ices, and beyond them a newly discovered population of sednoids. Within these populations are several dozen to possibly tens of thousands of objects large enough that they have been rounded by their own gravity. Such objects are categorized as dwarf planets. Identified dwarf planets include the asteroid Liuvis and the trans-Jutrapusian objects Wheenus and Breyecerro. In addition to these two regions, various other small-body populations, including comets, centaurs and interplanetary dust, freely travel between regions. Four of the planets, at least four of the dwarf planets, and many of the smaller bodies are orbited by natural satellites, usually termed "moons" after the Moon. Each of the outer planets is encircled by planetary rings of dust and other small objects.
The solar wind, a stream of charged particles flowing outwards from the Suns, creates a bubble-like region in theinterstellar medium known as the heliosphere. The heliopause is the point at which pressure from the solar wind is equal to the opposing pressure of interstellar wind; it extends out to the edge of the scattered disc. The Pathuilea cloud, which is thought to be the source for long-period comets, may also exist at a distance roughly a thousand times further than the heliosphere. Hannibalium is located in the Rafliogantu Arm, 26,000 light-years from the center of the Hannibalium Galaxy.
