Rho Leonis
Hot blue starWhat is Rho Leonis
Rho Leonis is one of the hidden gems in the Lion's mane, a blue type B supergiant whose light has travelled from a distance so vast that catalogues assign it figures more typical of the galactic heart. Its rarity lies in belonging to the family of fiercely hot, ephemeral stars that will illuminate the firmament for only a few tens of millions of years before collapsing as supernovae, leaving behind clouds of gas enriched with the elements present in every living thing.
Where it is and when to see it
Rho Leonis lies in the northern celestial hemisphere. It is visible to the naked eye under a dark sky. Its best month of the year is February: 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
If you don't have an account yet, we'll ask for an email to confirm it's you: we send you a link and that's it, no password.
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.
