Seriously, the bright star that rises after the Moon and, as the Earth rotates, follows the Moon across the sky toward the west is the heart of Leo the Lion, the star Regulus. The animated graphic below shows the stars of Leo and the waxing gibbous Moon at 9 pm local time. All of the stars forming the asterism shape for Leo, the backward question mark and triangle, are labeled, and the stars are connected with lines to show the constellation pattern.
In the third image of the 3-picture sequence the triangle forming the lion’s tail is not drawn but the star Denebola, making the triangle’s point, is used as one of the four corners for the ‘Diamond of Virgo’ asterism. The opposite corner of the ‘diamond’ is the reddish star Arcturus belonging to the constellation Bootes the Herdsman. The upper star of the diamond is Cor Caroli, on of the stars belonging to the constellation Canes Venatici, the ‘Hunting Dogs’ used by Bootes to drive off a bear according to one sky story. And off to the left are the seven stars making the asterism the Big Dipper, part of Ursa Major ‘the Great Bear’.
