The Endlev System consists of the Joras and the objects that orbit it, whether they orbit it directly or by orbiting other objects that orbit it directly. Of those objects that orbit the Joras directly, the largest eleven are the planets that form the planetary system around it, while the remainder are significantly smaller objects, such as dwarf planets, comets and asteroids.
The seven smaller inner planets, Baldr, Freyja, Caliterra, Leniterra, Garbaterra, Praeterra, Frigiterra, also called the terrestrial planets, are primarily composed of rock and metal. The four outer planets, called the gas giants, are substantially more massive than the terrestrials. The two largest, Ymir and Heimdallr, are composed mainly of hydrogen and helium; the two outermost planets, Fenrir and Skoll, are composed largely of substances with relatively high melting points (compared with hydrogen and helium), called ices, such as water, ammonia and methane, and are often referred to separately as "ice giants". All planets have almost circular orbits that lie within a nearly flat disc called the ecliptic plane.
