Cererian

Sprinkled with salt and Cererean grain

An untilled soil its yearly growth of grain Cererian yields

As a divinity of the earth, Mefitis shows in fact two aspects: cererian, she is goddess of plowing [...], and chthonian

We find, for example, at Agnone a "Cererian" Hercules and at Rossano a "Mefitanian" Mamers (= Mars); presumably these two major Italic divinities, Hercules and Mamers, were the "guests" of Ceres and Mefitis

Most of the ship's mass would be Cererian water; Earth would supply the crew, the ship's skin, and the engines. Ceres' surface gravity is about ¹/₃₆ Earth's gravity, and the asteroid is just close enough to the sun for it to power the machinery. Cererian water may unlock the solar system.

Brucite itself has not been observed in meteorites in the amounts implied by Ceres' spectrum, which seems to minimize the likelihood that any Cererean material has been found by meteorite hunters.

Vesta is the brightest asteroid visible from Earth and its maximum distance from the Sun is slightly farther than the minimum distance of Ceres from the Sun (2.56AU). However its orbit lies entirely within the Cererian orbit.

Future, home-born Cererians will presumably become better adapted to their low gravitational environment
