Tau-Ceti

Tau Ceti (τ Cet, τ Ceti) is a star in the constellation Cetus that is spectrally similar to the Sun, although it has only about 78% of the Sun's mass. At a distance of just under 12 light-years from the Solar System, it is a relatively nearby star, and is the closest solitary G-class star. The star appears stable, with little stellar variation.

Tau Ceti is metal-deficient, a deficiency usually associated with systems having no giant planets and few terrestrial planets. Observations have however detected more than ten times as much dust surrounding Tau Ceti as is present in the Solar System.

Since December 2012, there has been evidence of possibly five planets orbiting Tau Ceti, with one of these being potentially in the habitable zone. Because of its debris disk, any planet orbiting Tau Ceti would face far more impact events than Earth.

It can be seen with the unaided eye as a third-magnitude star. As seen from Tau Ceti, the Sun would be a third-magnitude star in the constellation Boötes.

Differences between the fictional and physical systems
There are 5 planets orbiting Tau Ceti. While in reality none of the planets detected in 2012 have similar mass or orbital period compared to Earth, in the Midoria Files Universe, the third planet called Midoria, has a mass and orbital period similar to Earth's. This change was necessary and therefore considered an artistic license by the author.
