Hipparchus Research Papers

During the historical period of Hipparchus, the Earth was a place where the stars were more amplified in ways than what they are these days – even with the great Hubble Space telescope. Having no telescope, Hipparchus came up with the brilliant idea concerning discerning and calculating correctly the duration of the sidereal and solar years, along with meticulously mapping out the stars. In all likelihood, the setting of Rhodes around 100 BC was the only place where a man could do this using only his mind. Hipparchus, the first great observational astronomer, was born around 194 BC, in Nicaea which is today a part of the coast of Turkey. We don’t know much about Hipparchus’ life, but that he left Alexandria in the great cataclysms of 150 BC. After that, most of his life was spent on the Greek island of Rhodes, where he carried out his astronomical observations over a 30-year period . The only tool deployed by Hipparchus except for his unaided eyesight, was a rod, which could be rotated about the vertical and was directed toward the object observed; the angle to the vertical could be measured against a circle with demarcated degrees. Hipparchus died on Rhodes around 120 BC. We can be certain that much time was spent by Hipparchus looking at the stars, because it is suggested by the volume of his observational astronomy. Hipparchus’ errorless and meticulous mapping of the stars is considered to be his greatest astrological achievement. Before Hipparchus, the stars had been mapped out in a bit slipshod but poetic manner.
