Script error: No such module "Check for unknown parameters".

XZ Tauri is a binary system approximately Script error: No such module "convert". away in the constellation Taurus. The system consists of two T Tauri stars orbiting each other about 6 billion kilometers apart (roughly the same distance as Pluto is from the Sun). The system made news in 2000 when a superflare was observed in the system.

A third star, component C, has been observed at a separation of Script error: No such module "val"., but subsequent observations failed to find it.[10][8] The T Tauri star HL Tauri, Script error: No such module "val". away, is also sometimes listed as a companion.[9]
