The planet known for its blue color is Earth. This distinctive appearance is primarily due to the vast oceans that cover approximately 71% of its surface. Water absorbs colors in the red part of the light spectrum and reflects the blue, giving Earth its characteristic blue hue when viewed from space. Additionally, the presence of the atmosphere scatters sunlight, contributing to the blue visual we often associate with our planet. Earth is unique not only for its color but also for its ability to support life, thanks to its water, atmosphere, and suitable temperature ranges.
