What was discovered
Lists of asterisms with measured star positions and observations of the planets. Together with that of Wu Xian, they form the basis of the 283 constellations of Chinese uranography.
It survives only in citations from the Kaiyuan zhanjing (8th century); the surviving coordinates may be Han revisions. The claimed observation of a moon of Jupiter by Gan De is highly speculative.
