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 six planets within the Tendor system. The four terrestrial or inner planets have dense, rocky compositions, few or no moons, and no ring systems. They are composed largely of refractory minerals, such as the silicates, which form their crusts and mantles, and metals, such as iron and nickel, which form their cores. The two outer planets, or gas giants, consist overwhelmingly of hydrogen and helium, both gas giant planets have rings which are easily observable. Aurious, which has the more prominent rings mainly consist of dust, rock and particles range in size from micrometers to meters while the smaller and less prominent rings of Tsanfau mostly consist of ice and some radiation-processed organics.
