Mercury: grey. Venus: yellowish-white. Earth: light blue with white clouds; oceans and light scattered by the atmosphere make Earth prevailingly blue. Mars: red-orange. Jupiter: has orange and white bands; the white bands are colored by ammonia clouds, while the orange comes from ammonium hydrosulfide clouds. Saturn: pale yellow; ammonia haze covers the whole planet and obscures redder clouds below. Uranus: light blue; the color comes from methane clouds.
Venus is the second planet from the Sun, orbiting it every 224.7 Earth days. It has no natural satellite. It is named after the Roman goddess of love and beauty. After the Moon, it is the brightest natural object in the night sky, reaching an apparent magnitude of â4.6, bright enough to cast shadows.his makes the Venusian surface hotter than Mercury 's, which has a minimum surface temperature of 55 K (â220 Â°C) and maximum surface temperature of 695 K (420 Â°C), even though Venus is nearly twice Mercury's distance from the Sun and thus receives only 25% of Mercury's solar irradiance.
