We present calculations of the Cosmic X-ray background (CXB) reflection by the Earth atmosphere in the 1-1000 keV range and compare it with the reflection by the Moon and the Sun. The calculations use realistic chemical composition of the Earth atmosphere and include all relevant physical processes. An analytic approximation to the Earth X-ray albedo is provided, which should be accurate down to few percent level in the range from few keV up to few hundred keV.
