Abstract:

Goals of this paper are: to provide some basic descriptive statistical parameters for the apparent and absolute magnitudes of the nearby stars of spectral type G5V. Second, to establish the frequency functions and of the absolute and apparent magnitudes for these stars. Third, to compute the distance r of these stars as a system assuming that they scatter around a mean absolute magnitude in a Gaussian distribution. The accuracy of the numerical results is satisfactory.
