Earth is often referred to as the "blue planet" because that's exactly what it looks like from space - a blue planet!

The name also distinguishes Earth from all the other planets in the solar system, as none of those are blue. Besides, "the blue and green planet" just doesn't have the same ring to it!

Why Does Earth Look Blue From Space?
  • Our atmosphere is a bluish color - you can see that just by looking at the sky on a sunny day.
  • The Earth's surface is over 70% water, so from a distance - the kind of distance you'd get from looking at Earth from space - the planet looks blue.

The Earth is called a blue planet because, from space, it looks blue.

Another reason for Earth being referred to as the blue planet is because three-quarters of the surface is covered by oceans, while only a small part is land mass.

The fact that both the atmosphere and the oceans are blue is the reason that Earth is often called the blue planet.

Our atmosphere is blue, and so is water. There's a lot of water on Earth.
