Engineering is a popular and specialised industry. Electronics engineers design, develop and test components, devices, systems or equipment that use electricity as part of their source of power. These components include capacitors, diodes, resistors and transistors.
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 by far the hottest planet in the Solar System, with a mean surface temperature of 735 K (462 Â°C; 863 Â°F), even though Mercury is closer to the Sun. Venus is shrouded by an opaque layer of highly reflective clouds of sulfuric acid, preventing its surface from being seen from space in visible light.
