Parts manufactured for use on aircraft do face much tougher guidelines on design, construction, and quality control than those used in most industrial applications. A typical hydraulic pump used on an aircraft may cost between $4,000 and $25,000, compared with a comparable industrial pump's cost of $400 or less.
The temperature at the surface of the Sun is about 10,000 Fahrenheit (5,600 Celsius). The temperature rises from the surface of the Sun inward towards the very hot center of the Sun where it reaches about 27,000,000 Fahrenheit (15,000,000 Celsius).
Earth sits much closer to the sun than Mars does and is thus more intensely subjected to the sunâs formidable power. Not only does the sun generate temperatures on its surface upwards of more than 10,000Â° F (5,538Â° C), but its core temperature is over 27 million degrees Fahrenheit (15 million degrees Celsius)!
