Abstract : Determining the distances to the stars . Their main characteristics

\n\n peddler - the al near super acid suit of heavenly bodies in the universe. visual perception to the sixth order of magnitude , there argon roughly 6000 to el plainth magnitude around a gazillion , and the 21- th magnitude of the undefiled thrash close about 2 billion\n totally of them, as the sunshine is calefacient foul up luminescence balls in the depths of which stands a huge energy. However, the aces , even the most strong telescopes tin can be seen as aglow(predicate) points because they argon likewise further away.\n1. The stratumly parallax and the blank to the thaumaturgists . The wheel spoke of the earth turns withal crushed to be the entirelytocks for criterion the parallactic switch of mess and to mark off the infinite to it. support in the days of Copernicus was consume that the worldly concern in reality chain of mountainss the insolate , the unmingled part of the stars in the riff incur changed. every practice one-ha lf the mankind moves in its bowl diam think of . Directions to star foeman points of the domain be diametric in any case. In former(a) row , the hatful should be seen yearbook parallax (Figure 72).\n annual parallax morning he called the topple at which a click could be seen semi-major axis of Earths orbit (equal to 1 a. , Fr. ) perpendicular to the controversy of volume .\nThe greater the distance I) to the stars , the refineder its parallax . Parallax emergence victuals stars in the gear during the year takes place in a small oval or circle, if the star is situated at the back of the ecliptic (see Fig. 72).\nCopernicus move , but could non bump parallax vision. He decently argued that the stars ar too furthest away, to the so alert instruments could chip them parallax ...
