About Leo Minor

Leo Minor was introduced by the Polish astronomer Johannes Hevelius, who drew a small lion above the great one from the faint stars between Leo and Ursa Major. When Greek letters were later assigned to its stars, the brightest was overlooked, so the constellation has a Beta but no Alpha.

That brightest star is Praecipua, an orange giant whose Latin name means the chief. The figure is a short chain of faint stars that needs a dark sky to trace. Leo Minor is best seen on spring evenings in the northern hemisphere, high in the sky above the sickle of Leo.

What you see in the piece

This is one of the shallower figures: the farthest of its stars is not so much farther than the nearest. Even so, flown out to, the little lion loses its shape as the stars separate in depth.
