Cestus IV used to be a class Q planet with an irregular orbit that caused temperature drops of more than 150 ° C. In 2348, a huge asteroid fragment struck the planet, diverting the planet from its orbit and settling the planet in the Ecosphere. As a result, after the dust stabilized in the atmosphere after the planetary collision, the temperatures on the planet stabilized. The collision also caused geological changes and allowed the formation of rich deposits of dilithium crystals. The orbit is now maintained in the habitable zone and one cycle lasts 9 months, 18 days. In 2385, the first mining base on the planet was built, by the federal mining company CMC.
