Since the values for the solar constant k s earth s albedo and the stefan boltzmann constant σ are all known it is possible to solve this equation for temperature t.

The solar constant for a planet is s.

Solar constant the total radiation energy received from the sun per unit of time per unit of area on a theoretical surface perpendicular to the sun s rays and at earth s mean distance from the sun. It is most accurately measured from satellites where atmospheric effects are absent. What is the surface temperature for a planet with no atmosphere with a solar constant of 2 718 w m 2 and an albedo of 0 6. It is measured on a surface perpendicular to the rays one astronomical unit au from the sun roughly the distance from the sun to the earth.

The solar constant includes all types of solar radiation other than neutrinos not just the visible light. The sun subtends an angle theta at the planet. The value of the constant is approximately 1 366 kilowatts per square metre. The surface temperature of the sun is tk.

The solar constant is the amount of solar radiation incidence that is received at a distance of 1 astronomical unit au from the sun. Earth s overall average albedo is about 0 31 or 31. The solar constant is calculated by multiplying the sun s surface irradiance by the square of the radius of the sun over the average distance between the earth and the sun. Solar constant the total radiation energy received from the sun per unit of time per unit of area on a theoretical surface perpendicular to the sun s rays and at earth s mean distance from the sun.

Due to the fact that the earth rotates around the sun and it s distance depends on the time of year the actual direct solar incidence that earth receives varies. Using a little more algebra we can write the expression above as. It is presently calculated as being 1 366 w m2. Irradiance is sometimes referred to as flux and is a measurement of electromagnetic energy from the sun.

The solar constant for a planet is s. The solar system is the gravitationally bound system of the sun and the objects that orbit it either directly or indirectly.
