The planets in the Solar System are all in different colors. The colors of the planets are related to which substances, the surfaces and the atmosphere it consists of.
Mercury has a rocky surface and very thin atmosphere. Because covered by a thick layer of rock and dust which is formed as a result of volcanic activity and containing silicon and iron in large quantities, Mercury appears dark gray.
Venus, whose atmosphere is composed of carbon dioxide and covered with a thick cloud layer containing sulfuric acid, appears in yellow-orange color.
The Earth is one of the blue members of the Solar System, with about 70% of its surface covered with water. The Earth appears blue from space but it’s possible to notice other colors like white and green if examined in more detail.
The reason for the appearance of Mars in red-orange colors is that its surface is covered with rocks containing iron compounds and dust particles.
The atmosphere of Jupiter is largely hydrogen and helium. It also contains water droplets, water crystals, ammoniacal crystals. In the atmosphere of Jupiter, occur severe storms which are over 600 kilometers per hour. The white-light yellow colors on the surface of Jupiter originate from ammonia crystals in the clouds. The parts appearing in brown-orange color are the areas containing ammonium hydrosulfide clouds.
The composition of Saturn’s atmosphere is similar to Jupiter’s. However, the ammonia layer surrounding the planet causes colors in the lower parts of the red clouds to appear more pale.
The reason why Uranus appears blue-green is methane in its atmosphere. Methane which is absorbing the red light at a wavelength of 600 nanometers, reflects the rays at the other wavelengths of light that make up the light spectrum.
The composition of the atmosphere is similar to Uranus, but the color of Neptune is bright blue. The reason why Neptune appears bright blue is an unknown substance in its atmosphere.
