The planet known for its bright blue color is Earth. This distinct color is primarily due to the vast oceans that cover approximately 71% of the planet's surface, reflecting sunlight in a way that appears blue from space. Additionally, Earth's atmosphere scatters sunlight, contributing to the blue hues observed from orbital perspectives. The combination of landmasses, water bodies, and atmospheric conditions gives Earth its unique appearance, making it often referred to as the “Blue Planet.” This visual characteristic has made it a subject of fascination for astronomers and a symbol of life and biodiversity for those on the planet.
