Iota Horologium
What is Iota Horologium
Iota Horologii is a yellow G-type star much like the Sun, lying only 56 light-years away in the small southern constellation of the Clock. Its astronomical importance is real: it hosts at least one confirmed gas-giant planet, discovered in 1999 by radial velocities, in an orbit of just over 300 days. It also belongs to the Hyades stellar stream, a kinematic current linked to the open cluster that adorns Taurus.
Where it is and when to see it
Iota Horologium lies in the southern celestial hemisphere. It is visible to the naked eye under a dark sky. Its best month of the year is October: 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.
