Aristarchus The first of the Greek philosphers and mathematicians to unravel the celestial plan and announce the discovery was Aristarchus of the isle of Samos. Others before him assumed that the Earth is a sphere and that it moves, but he was the first to formulate plainly the heliocentric theory, the scheme which has the Sun in the center. Aristarchus lived from about the year 310 before the present era to about 230, and among the geometers he succeeded Euclid and preceded Archimedes. In -288 or -287 he followed Theophrastus as the head of the Peripatetic School established by Aristotle. Whatever his scientific argument may have been, he accused Aristarchus of an act of impiety. Plutarch wrote in his book Of the Face in the Disc of the Moon (De facie in orbe lunae) We do not know whether there was any actual court action and verdict; however, we know that a verdict of judges, even if unanimous, could not make the Sun a satellite of the Earth. Not even a scientific tribunal can do this, not even if it is presided over by Archimedes and the most illustrious men of the generation sit as judges. Aristarchus had no followers in his generation, nor in the next generation. About a century after Aristarchus, Seleucus, a Chaldean of Seleucia on the Tigris, who lived and wrote about the year 150 before the present era, adopted the teaching of Aristarchus.

ARISTARCHUS OF SAMOS AND THE HELIOCENTRIC UNIVERSE Aristarchus of Samos ( ca. B.C. ), called "the mathematician" during his life, is the first person known to have proposed our modern view of the universe: that the Earth revolves around a fixed Sun. For some reason, however, Copernicus, who wrote 1700 years later and knew of Aristarchus' work, is the person most often credited with this heliocentric theory. Being far ahead of his time, like his younger contemporary Archimedes, his ideas never seem to have developed a following and so died out until the telescope revived them. Unfortunately, the original work in which Aristarchus proposes the theory has been lost; we know of it because Archimedes refers to it and describes Aristarchus' proposals. Unlike some ancient scholars, whose seemingly modern views were part of a larger system of mysticism and religion, Aristarchus was firmly grounded in observation and mathematics. The heliocentric theory is thought by some to have been a natural exension of his finding that the Sun is much larger than the Earth. His major extant work, On the Sizes and Distances of the Sun and Moon

Based upon his measurement and calculation of the size of the sun, Aristarchus advanced a heliocentric hypothesis 17 centuries before Copernicus Copernicus acknowledges this debt to Aristarchus in the early drafts of his On the Revolutions of the Heavenly Spheres but the reference does not appear in the published edition. Aristarchus argued that the lack of observed parallax in the fixed stars could be explained, within the heliocentric model, by assuming that the distance to the fixed stars was much larger than assumed.

Aristarchus of Samos (ca. 320-250 BC) Aristarchus was born on the island of Samos around 320 BC. He is believed to have studied and lived in Alexandria, where he died ca. 250 BC. A mathematician at least as much as an astronomer, he belonged to the so-called Pythagorean school of thought, which sought to understand the universe in terms of geometrical and arithmetical relationships. Aristarchus' only surviving text is his Treatise on the Sizes and Distances of the Sun and Moon . However, largely through the writings of Archimedes (287-212 BC) and Plutarch, Aristarchus is known to have the first proponent of the heliocentric hypothesis, with the Earth ascribed a movement of orbital rotation about the Sun, as well as a daily axial rotation. Aristarchus argued that the lack of observed annual parallax in the fixed stars could be explained, within his heliocentric model, by assuming that the distance to the fixed stars is very much larger than the size of the Earth's orbit. The very same argument was to be made by Nicholas Copernicus , seventeen centuries later.

Aristarchus of Samos (c. 320-c. 250 BC) Greek astronomer. The first to argue that the Earth moves around the Sun, he was ridiculed for his beliefs. He was also the first astronomer to estimate (quite inaccurately) the sizes of the Sun and Moon and their distances from the Earth. Aristarchus was born on Samos and may have studied in Alexandria, where he died. Aristarchus' only surviving work is Magnitudes and Distances of the Sun and Moon. He produced methods for finding the relative distances of the Sun and Moon that were geometrically correct but rendered useless by inaccuracies in observation. Aristarchus' model of the universe described the Sun and the fixed stars as stationary in the cosmos, and the planets - including the Earth - as travelling in circular orbits around the Sun. He stated that the apparent daily rotation of the sphere of stars is due to the Earth's rotation on its axis as it travels along its orbit, and that the reason no stellar parallax (change in position of the stars) was observed from one extreme of the orbit to the other is that even the diameter of the Earth's orbit is insignificant in relation to the vast dimensions of the universe.

Aristarchus Of Samos (c. 310-230 BC), Greek astronomer, first to maintain that the Earth rotates and revolves around the Sun. On this ground, Cleanthes the Stoic declared that he ought to be indicted for impiety. Aristarchus' advanced ideas on the movement of the Earth are known from Archimedes and Plutarch ; his only extant work is a short treatise, " On the Sizes and Distances of the Sun and Moon. " The values he obtained, by using geometry, are inaccurate, because of faulty observations. Aristarchus found a more precise value for the length of the solar year. A lunar crater is named for him; a peak in its centre is the brightest formation on the Moon. (C) 2000 Britannica.com Inc. Until the 16th century, most people (including early astronomers) considered Earth to be at the center of the universe. Greek philosopher Aristotle proposed a cosmology in about 350 bc that held for thousands of years. Aristotle theorized that the Sun, the Moon, and the planets all revolved around Earth on a set of celestial spheres. These celestial spheres were made of the quintessence—a perfect, unchanging, transparent element. According to Aristotle, the outermost sphere was made of the stars, which appear to be fixed in position. Early astronomers called the stars “fixed stars” to differentiate between stars and planets. The spheres inside the sphere of the fixed stars held the planets, which astronomers called the “wandering stars.” The Sun and Moon occupied the two innermost spheres. Four elements (earth, air, fire, and water) less pure than the quintessence made up everything below the innermost sphere of the moon.
