  ABSTRACT: In this paper, an intrinsic relation was developed for Hyades stars between a function of the right ascensions α and declination δ with the angular distance λ from the vertex. The precision criteria of this relation are very satisfactory and a correlation coefficient of value ≈ 1 was found which proves that the attributes are completely related linearly.
