Solar wind
The original application of the Compton–Getting effect predicted that the intensity of cosmic rays should be higher coming from the direction in which Earth is moving. For the case of cosmic rays the Compton–Getting effect only applies to those that are unaffected by the Solar wind such as extremely high energy rays. It has been calculated that the speed of the Earth within the galaxy () would result in a difference between the strongest and weakest cosmic ray intensities of about 0.1%.
