4 Arietis
Hot blue starWhat is 4 Arietis
4 Arietis is a hot blue B-type star within the Ram, the first sign of the zodiac and the ancient vernal point where the Sun crossed the celestial equator in Greek antiquity. Its surface burns well above ten thousand kelvin, shining with the blue-white typical of massive, youthful stars. At 275 light-years, its light set out around 1750, when Kant was publishing his Universal Natural History and Theory of the Heavens, speculating on the nature of the nebulae.
Where it is and when to see it
4 Arietis lies in the northern 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.
