The Earth is the only planet in the solar system where this is true. Part of the reason for this results from the distance from the Sun. But, the reason that temperature remains fixed is controlled by the atmosphere. Solar Radiation and the Atmosphere Radiation reaching the Earth from the Sun is electromagnetic radiation. Electromagnetic radiation can be divided into different regions depending on wavelength.
Earth receives all wavelengths of solar radiation.
But certain gases and other contaminants in the atmosphere have different effects on different wavelengths of radiation. In addition trace gases have an effect. O. Some of the O then recombines with O 2 to make O 3 . This O can then can recombine with O 2 to make more Ozone. The process is self regulating and results in less ultraviolet radiation reaching the Earth's surface.
