Adrastea

(Moon in the Sol System, Privately Owned by the Khan Family and used as Family Seat.) Population: 1550 (Family and Servants)

( /ˌædrəˈstiːə/ AD-rə-STEE-ə; Greek: Αδράστεια), also known as Jupiter XV, is the second by distance, and the smallest of the four inner moons of Jupiter. It was discovered in Voyager 2 probe photographs taken in 1979, making it the first natural satellite to be discovered from images taken by an interplanetary spacecraft, rather than through telescopic photography. It was officially named after the mythological Adrasteia, foster mother of the Greek god Zeus—the equivalent of the Roman god Jupiter. Adrastea is one of the few moons in the Sol System known to orbit its planet in less than the length of that planet's day. It orbits at the edge of Jupiter's Main Ring and is thought to be the main contributor of material to the Rings of Jupiter. Adrastea has an irregular shape and measures 20×16×14 km across. Surface area 1,600  km2. This makes it the smallest of the four inner moons.

Adrastea is the smallest and second closest member of the inner Jovian satellite family. It orbits Jupiter at a radius of about 129,000 km (1.806 Jupiter radii) at the exterior edge of the planet's Main Ring. Adrastea is one of only three moons in the Solar System known to orbit its planet in less than the length of that planet's day—the other two being Jupiter's innermost moon Metis, and Mars' moon Phobos. The orbit has very small eccentricity and inclination—around 0.0015 and 0.03°, respectively. Inclination is relative to the equator of Jupiter. Due to tidal locking, Adrastea rotates synchronously with its orbital period, keeping one face always looking toward the planet. Its long axis is aligned towards Jupiter, this being the lowest energy configuration.

The orbit of Adrastea lies inside Jupiter's synchronous orbit radius (as does Metis’s), and as a result, tidal forces are slowly causing its orbit to decay so that it will one day impact Jupiter.

One of the richest and oldest Sol System dynasties are the Khan Family. Rupree Khan made a fortune in selling mining equipment to Asteroid Miners and the Khan Family still maintains a large Mining Equipment Distributor warehouse on Ceres.

The Khan Family claimed Adrastea and transformed it into a lavish Family palace with a small army of servants. No uninvited approach is permitted.
