Abstract
Solar motion is determined by using radial velocities of the Hipparcos Catalogue, for distances between 10 pc and 100 pc and different values of color index; 3,362 stars with radial velocities and color index were chosen and different groups were formed as a function of the distance from the Sun in intervals of 10 pc, until 100 pc. For this reduction, the least squares method has been applied. Since the sample was small, the results show a great dispersion with respect to literature data. The average gives an acceptable result: V⊙ = 25.3.
