Preserved in the cave excavations of Mogao
and listing 1,339 stars the Dunhuang Star Chart
is the oldest graphical star atlas
known to exist. Dated to between 649 and 684 AD, it features two sections. The first consists of 26 diagrams of asterisms (including a recognizable Big Dipper and Orion) and the second contains 12 star maps each showing a 30 degree east-west section of sky in cylindrical projection plus an azimuthal projection circumpolar map. Star positions are accurate to within 1.5 degrees and it includes some stars in the southern sky.
