What is Iota Chamaeleon

Iota Chamaeleontis is a yellow-white F-type star in Chamaeleon, in the deep south near the celestial pole. At about 188 light-years, it radiates twenty times the Sun's light from a surface at 6,429 K. Its most singular feature is invisible to the eye: an infrared excess betrays a disc of dust orbiting at some eight astronomical units, at 200 K — a possible scene of planet formation.

Where it is and when to see it

Iota Chamaeleon lies in the southern celestial hemisphere. It is visible to the naked eye under a dark sky. Its best month of the year is May: 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.
