Only the sun radiates heat

WebThe Earth radiates energy at wavelengths much longer than the Sun because it is colder. The Earth absorbs most of the energy reaching its surface, a small fraction is reflected. In total approximately 70% of incoming radiation is absorbed by the atmosphere and the Earth’s surface while around 30% is reflected back to space and does not heat the surface.
