What is Omicron Coronae Borealis

Omicron-1 Coronae Borealis hosts a confirmed planet: one of the least massive worlds ever detected around a red clump giant. The star itself is an evolved K0 III, 270 light-years away, fusing helium at its core, with a radius ten times solar and fifty times the Sun's luminosity. The planet was revealed by the tiny radial wobbles it stirs in its host as it tugs gravitationally on the giant.

Where it is and when to see it

Omicron Coronae Borealis lies in the northern celestial hemisphere. It is visible to the naked eye under a dark sky. Its best month of the year is April: 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.
