The 88 constellations

The sky is divided into 88 constellations, the ones the International Astronomical Union fixed. Stelvia's 5,070 catalogued stars are spread across them: every star visible to the naked eye, down to magnitude 6. Each constellation has its own page.

Northern sky (29)

Their median declination lies north of the celestial equator: they are best observed from the northern hemisphere.

Around the celestial equator (13)

Their median declination lies within 10° of the celestial equator, so at some point in the year they can be seen from almost anywhere on Earth.

Southern sky (46)

Their median declination lies south of the celestial equator: they are best observed from the southern hemisphere.

These figures are computed over Stelvia's catalogue —stars visible to the naked eye, down to magnitude 6—, not over the constellation's real total: the count, the brightest and the nearest all refer to that catalogue. The region of the sky comes from the median declination of its stars; the month, from their mean right ascension.

A symbolic commemorative gift: neither the signature nor the chosen name implies ownership of the star or recognition by the IAU.
