Fornax

When and where to look for Fornax

Fornax crosses the meridian — its highest point in the sky — at local midnight around October, which makes the months from September to November the easiest time to find it in the evening. It spans declinations -32.4° to -29.0°, so visible from everywhere south of about 58°N.

The quickest way to find it is to open the live AR sky map and point your phone at the sky — if Fornax is above your horizon right now, its figure is drawn in the position it genuinely occupies above you.

Brightest stars in Fornax

Magnitude runs backwards: lower numbers are brighter, and anything below about 6.5 is beyond the naked eye under a dark sky.

What Fornax is made of

The catalogue lists 62 stars within Fornax, of which 62 are magnitude 6.5 or brighter — the limit of what an unaided eye picks up under a genuinely dark sky. The rest need binoculars or a telescope.

Spectral make-up

Spectral class is a temperature ordering, running from O at around 30,000 K down to M below 3,500 K. A constellation is a direction, not a group, so this is simply what happens to lie along that line of sight.

The closest catalogued star in this direction is HD 14412 at 41.3 light years. The most distant is HD 22322 at roughly 1,152 light years — stars that appear side by side here are nothing of the sort.
