Variable star

Its story

Upsilon Tauri belongs to the Hyades, the elder sisters of the Pleiades and the closest open cluster to the Sun, about 154 light-years away. It is a rare Delta Scuti variable pulsating every 3.6 hours, and one of the cluster's giddiest gyroscopes: a full rotation every 0.4 days, equator racing at 243 km/s. Young, fast, throbbing.
