WebBecause of the greenhouse effect, the Earth's actual average surface temperature is about 288 K (15 °C), which is higher than the 255 K effective temperature, and even higher than the 279 K temperature that a black body would have. In the above discussion, we have assumed that the whole surface of the earth is at one temperature. Blackbody temperature To find the effective (blackbody) temperature of a planet, it can be calculated by equating the power received by the planet to the known power emitted by a blackbody of temperature T. Take the case of a planet at a distance D from the star, of luminosity L. Assuming the star … See more The effective temperature of a body such as a star or planet is the temperature of a black body that would emit the same total amount of electromagnetic radiation. Effective temperature is often used as an estimate of a … See more The effective temperature of a star is the temperature of a black body with the same luminosity per surface area (FBol) as the star and is defined according to the Stefan–Boltzmann law FBol … See more • Star portal • Brightness temperature • Color temperature See more • Effective temperature scale for solar type stars • Surface Temperature of Planets • Planet temperature calculator See more

Webof the Sun is fitted to the black body curve by using Tas a free parameter, we deduce that the blackbody temperature of the sun is about 6000K. Let us consider the energy balance of the Earth as in Fig.2.5, which shows the Earth intercepting the solar energy flux and radiating terrestrial energy away. WebOpen the blackbody radiation applet Select a temperature by moving the slider Click on the x- and y-axis zoom in and zoom out buttons until the blackbody emission spectrum becomes visible. Typical choices: Sun: x-axis: 0 to 3 and y-axis: 0 to 100; Earth: x-axis: 0 to 48 and y-axis: 0 to 0.0001 dpi700 druck
