Tau8 Serpentis, Latinized from τ8 Serpentis, is an A-type main sequence star in the constellation of Serpens, approximately 364 light-years from the Earth.[5] It has an apparent visual magnitude of approximately 6.144.[5] Although it was observed to be binary by speckle interferometry in 1985, subsequent observations show no sign of binarity, and the detection appears to have been spurious.[8]
