Saad AlJanabi Holland University / DenHaag Research in physics / astronomy. ============================================== measurement of Mass Star To discuss the issue of measurement the mass of star is probably difficult, and the reason is due to the lack of being able to do the work of micro-precision computational results required, in view of the way in which grows by the star and even die. The scientists and researchers think the way that can be calculated mass of the star, which gives results accurate to denounce mass star. We can account by the mass of the sun by which it's effectuation amount of gravity on Earth. We also do not know whether other stars have the planets, as is the case of the sun. Or not? There are a lot of stars groupes are Constellations bilateral, and studies show that more than one third of the stars of this kind in the solar space. Th recipe rotation with orbite of hi e axis of rotation of the stars bilateral one on the other, and naturally, the dark star is rotating about Shining Star, which is a source for him. The star can be monitored in the accompanying with his sun at the same time .
