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).
1 Really hot. 2  The visible surface of the Sun, called the photosphere, has a temperature of about 5800 Kelvin. 3  That's equivalent to roughly 10,000 Fahrenheit. 4  Any solid substance placed in the photosphere would rapidly melt and evaporate into gas.5  The Sun is big.6  Really big.
