Rho Tauri (ρ Tau, ρ Tauri) is a star in the constellation Taurus and a member of the Hyades star cluster.[7]

Rho Tauri is a white A-type main sequence dwarf with a mean apparent magnitude of +4.66. It is approximately 158 light years from Earth. Classified as a Delta Scuti type[7] variable star, its brightness varies by 0.010 magnitudes over a period of 1.61 hours.[4]

It has 1.88 times the mass of the Sun, with a projected rotational velocity of 117 km/s and an estimated rotation period of 488.5 days.[6]
