Star System UX-17 is a star system charted by Kitsurugi Uesu during his departure from Central Yamatai. This system has no habitable worlds but is heavily used as a mining area, supplying raw materials for Yamataian shipyards. It is located in the Ketsurui Military Sector. There is a Frontier Starport located on the third planet. It was built in YE 32.

The Yamatai Star Empire placed global communications networks of Emrys Satellites into orbit of all of the system's terrestrial worlds in YE 36.

Sunrise Station was located in this system.

In YE 36, this system became part of the PAINT public transportation system and has a Tenba that regularly visits and provides passenger flights to Shinjuku Starport on Hanako's World.

In YE 38, Trinary Star Shipping established a storefront in the mining colony.

In YE 41, this star system was conquered by forces from the Interstellar Kingdom Of Kuvexia during the Kuvexian Invasion of YE 41.
