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.
