What is 66 Tauri

66 Tauri stands in the wide field of the Bull, a white A-type star whose clean, hot light travels 396 years before reaching us. It left when Velázquez was painting at the court of Philip IV. With no notable pulsations and no known companions, it offers the cleanest image of a star in its maturity: a sphere of hydrogen in silent combustion, bright as a magnesium flame.

Where it is and when to see it

66 Tauri lies in the northern celestial hemisphere. It is visible to the naked eye under a dark sky. Its best month of the year is November: the Sun sits at the opposite point of the sky and the star culminates around midnight. How high it climbs above the horizon depends on the latitude you watch from.

The signature wall

Stelvia's sky works like a signature wall: anyone can leave their name and a message on a real star, and that signature goes up on the map for everyone to read. Signing is free.

A signature without a lock can be replaced by someone else's. The lock makes the signature permanent and lets you choose a symbolic name for the star, always shown next to the star's catalogue identifier. How the lock works

Write my signature

A public signature from a real person. The chosen name is a symbolic denomination within Stelvia, with no official standing or IAU recognition: the sky is not for sale and belongs to no one.
