What were some of Aristarchus discoveries?
Aristarchus used clear logic to estimate the size of the Earth, the size and distance to our Moon, the size and distance to our Sun, then he even deduced that the points of light we see at night are not dots painted on some celestial sphere but stars like our Sun at enormous distances.
What was Aristarchus most famous discovery?
Aristarchus was certainly both a mathematician and astronomer and he is most celebrated as the first to propose a sun-centred universe. He is also famed for his pioneering attempt to determine the sizes and distances of the sun and moon.
What three conclusions did Aristarchus make about the Sun?
His hypotheses are that the fixed stars and the Sun remain unmoved, that the Earth revolves about the Sun in the circumference of a circle, the Sun lying in the middle of the orbit, and that the sphere of the fixed stars, situated about the same centre as the Sun, is so great that the circle in which he supposes the …

Which scientist from the Renaissance period made significant scientific discoveries?
Scientists like Francis Bacon, Galileo, Rene Descartes, and Isaac Newton made discoveries that would change the world. The most important invention of the Renaissance, and perhaps in the history of the world, was the printing press.
How did Aristarchus make his discovery?
Aristarchus was one of the first astronomers to calculate the relative sizes of the Sun, the Moon and the Earth. He did this by observing the Moon during a lunar eclipse and by estimating the angle and the size of the Earth.
How did Aristarchus of Samos come up with his theory?
He was influenced by Philolaus of Croton, but Aristarchus identified the “central fire” with the Sun, and he put the other planets in their correct order of distance around the Sun. Like Anaxagoras before him, he suspected that the stars were just other bodies like the Sun, albeit further away from Earth.
What did Aristarchus do to become famous as an astronomer?
What Aristarchus Achieved. Aristarchus is best known for two things: his belief that Earth orbits (revolves) around the Sun and his work attempting to determine the sizes and distances of the Sun and Moon relative to each other.
Where did Strato of Lampsacus study Aristarchus?
Aristarchus was born on Samos island. He probably studied in Alexandria, Egypt, under Strato of Lampsacus. His only surviving work is entitled On the Sizes and Distances of the Sun and Moon. Aristarchus managed to place the Sun in the middle of the solar system and he also placed the planets in the right order from the Sun.
