Picture of the day
A lithograph by
Sidney Hall
depicting the constellations
Leo
and
Leo Minor
, two of the
88 modern constellations
. Although Leo was recognised as early as
Ptolemy
in the 2nd century AD, Leo Minor was only designated by
Johannes Hevelius
in 1687. As suggested by its name, Leo Minor is
considerably smaller
than Leo; the latter covers 947 square degrees, while the former only covers 232 square degrees.
Lithograph:
Sidney Hall
, from
Urania's Mirror
