This is why the sky appears blue in the day time as blue light with shorter wavelength gets scattered in all directions. For example- If you take a look at the close picture of Earth’s surface, it looks like light blue color at the area around the continents, whereas the deep areas of oceans look deep blue in color.ĭo you know that the ocean looks blue due to the reflection of the sky because the sky is blue in color? The sky appears blue in color because our atmosphere disperses blue light (which is of shorter-wavelength) quite efficiently as compared to red or orange light (which is of longer-wavelength). However, the blue color of the planet may vary depending on the depth of the oceans. Here on Earth, we take liquid water for granted after all, our bodies. Well, if you look at the images of Earth, most of its part looks blue which are the oceans present on Earth’s surface, whereas some other part looks brown or green which is actually the continents and the poles of Earth looks like white caps due to ice. Planet Earth has been called the Blue Planet due to the abundant water on its surface. A general statement about the blue appearance of Earth from outer surface is that “The Earth has almost 70% water on its surface due to which it looks blue in color”. You know, the second planet from the sun, where the clouds are shot through with sulfuric acid and the surface is hot enough to melt lead. July 11, 2013: Astronomers working with NASAs Hubble Space Telescope have deduced the actual color of a planet orbiting another star 63 light-years away. Dreaming of blue Orbiting at a distance of roughly 2.8 billion miles from the sun, Neptune is the furthest planet yet discovered in our solar system (that is, after Plutos. About 70 of the Earths surface is covered with water. Most of us are curious to know why the Earth is called a blue planet. The planet Earth is called the blue planet in our solar system.
