The Tendor System is the gravitationally bound system comprising the Sun and the objects that orbit it. Of those objects that orbit the Sun directly, the largest six are the planets with the remainder being smaller objects, such as dwarf planets and small Solar System bodies.

Planets

A planet is an astronomical body orbiting a star or stellar remnant that

• is massive enough to be rounded by its own gravity,
• is not massive enough to cause thermonuclear fusion, and
• has cleared its neighbouring region of planetesimals

There are seven planets within the Tendor system. The three inner terrestrial planets have dense, rocky compositions, few or no moons, and no ring systems; They are composed largely of refractory minerals, such as silicates, which form their crusts and mantles, and metals, such as iron and nickel, which form their cores. The three outer gas planets consist overwhelmingly of hydrogen and helium, and all possess rings of varying prominence. The rings of the gas giants Aurious and Nirduk mainly consists of dust, rock and particles ranging in size from micrometers to meters, while the rings of the ice giant Tsanfau mostly consist of ice and some radiation-processed organics. Bieruta, the fourth planet and a gas dwarf, is characterized by its gaseous exterior and rocky core, and theorized to be a failed gas giant due a lack of available material from its later formation.
