Tau Ceti (タウ星, Tau Sei) is a star in the Milky Way's Orion Arm, with a solar system of eight orbiting planets, known as the Tau Ceti system (タウ星系, Tau Seikei). One of the planets inhabiting this system is Sea of the Morning Star, Marika Kato's home planet.
Details[]
Tau Ceti is a G-type main-sequence star in the constellation Cetus. It is spectrally similar to the Earth's Sun, though it only has about 78% of the Sun's mass. It is considered a relatively nearby star, being just under 12 light-years from Earth and the Solar System.

Trivia[]
- The names used for the Star and the constellation in Japanese are a little different from the real Tau Ceti. Tau is rendered in Hiragana instead of Katakana, while Kujira (Whale) for Ceti is rendered in Kanji instead of Hiragana. Although it is still said to be in the Orion Arm.
- The real Tau Ceti has recently been found to have five planets - one of which (the fourth) is within the habitable zone.
- In Volume 7, the Silent Whisper started its FTL jump beyond the sixth planet's orbit - presumably this is where the gravitational pull of Tau Ceti is low enough to perform jumps.
