When and where to look for Lepus

Lepus crosses the meridian — its highest point in the sky — at local midnight around December, which makes the months from November to January the easiest time to find it in the evening. It spans declinations -22.4° to -12.9°, so visible from everywhere south of about 68°N.

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

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

What Lepus is made of

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 13Gam Lep at 29.1 light years. The most distant is Arneb at roughly 2,219 light years — stars that appear side by side here are nothing of the sort.
