Venus is the second planet from the Sun and is the second brightest object in the night sky after the Moon. It is often referred to as the 'morning star' or 'evening star' due to its brightness. In Greek mythology, Venus is associated with several figures, including URANIA, the muse of astronomy, VESPER, the goddess of the evening star, and Demilo, the goddess of love. These figures are all connected to the planet Venus, which is also known as the Morningstar and Eveningstar.
