Which planet is known as Blue planet?

What makes the Earth a blue planet when photographed from space?

Earth appears as a blue dot in the photograph primarily because of Rayleigh scattering of sunlight in its atmosphere. Earth is a pale blue dot, rather than dark blue, because white light reflected by clouds combines with the scattered blue light.

Is blue planet Earth or Neptune?

Neptune is another blue planet in our solar system whose atmosphere is made up of hydrogen, helium and methane. Methane is responsible for the blue colour of the planet. This is because methane in gaseous form absorbs all the red wavelength from the sun and only reflects blue wavelengths.

Why is Neptune blue?

The predominant blue color of the planet is a result of the absorption of red and infrared light by Neptune’s methane atmosphere. The images are part of a series of images made by Hubble during nine orbits spanning one 16.11-hour rotation of Neptune.

Who made Earth?

Formation. When the solar system settled into its current layout about 4.5 billion years ago, Earth formed when gravity pulled swirling gas and dust in to become the third planet from the Sun. Like its fellow terrestrial planets, Earth has a central core, a rocky mantle, and a solid crust.

However, the blue color of the planet may vary depending on the depth of the oceans.

Why is the ocean blue in color?

The ocean contains water in huge amount and the water molecules present in the ocean also absorb a certain wavelength of light. Water molecules also find easy to absorb blue light as it has shorter wavelengths, hence the ocean appears blue in color. In fact, if you click a picture inside water, it will appear completely bluish in color.
