HIP 6631
Cool red starWhat is HIP 6631
Within the small male Water-Serpent, Hydrus —that southern snake coiled near the celestial south pole— beats a red type M star, cool and veteran, far larger than the Sun yet of muted fire. Its light took roughly 904 years to cross the void: it set out when Europe was raising its first Romanesque cathedrals and al-Idrisi was charting the known world at the Sicilian court. It now arrives as an ancient and serene ember.
Where it is and when to see it
HIP 6631 lies in the southern celestial hemisphere. It is visible to the naked eye under a dark sky. Its best month of the year is August: 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

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.
