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).
The temperature patterns in the Sun are not well understood. The core has a very high temperature of more that 15 million degrees Kelvin. As you move away from the heat producing core the temperature drops to about 6000 degrees at the photosphere, the effective surface of the Sun.
