The planet named after the Roman goddess of love is Venus. In Roman mythology, Venus was associated with love, beauty, and fertility, and the planet embodies these traits through its dazzling brightness and striking appearance in the night sky. Venus is the second planet from the Sun and is often referred to as Earth's "sister planet" due to its similar size and composition. However, it has a thick, toxic atmosphere and surface temperatures hot enough to melt lead, making it very different from Earth. Its significance in mythology has made it a lasting symbol of love and beauty in various cultures.
