Overview of the planets in Rireinu (or Ano) system

The Rireinu planetary system consists of the nine planets orbiting Ano, the sun, together with their satellites and countless other orbiting bodies. Two of the planets, Rireinu and Minaere, have conditions suitable for terrestrial-type life.

In the diagram above you can see the relative sizes of the planets in comparison to Ano. Distances not to scale.

Amiere is a silicate planet with 0 moons. Its orbital period is 0.391499ye. or 129.7190pa., in galactic units ~121d. Its rotational period is 7ru25, in galactic units 16h 14min 24s. Its mean radius is 2,639.7km and its equatorial surface gravity is 3.704m/s2 or 0.378g.

Rireinu is an Earth analog with 1 moon (appropriately named Usa, or ‘moon’). Its orbital period is 1.000906ye. or 331.3pa., in galactic units ~300d.
