1. Aristarchus of Samos, reached two significant scientific conclusions. In one conclusion he estimated that the sun was at least 300 times larger than the earth. Although he greatly underestimated the sun's true size. In another conclusion, Aristarchus proposed that the earth & other planets revolve around the sun. Unfortunately for science, other astronomers refused to support Aristarchus's theories. Alexandria's last renowned astronomer, Ptolemy incorrectly placed the earth at the center of the solar system. Astronomers accepted this view for the the next 14 centuries.
2.The estimate that was closest to modern measurment is that Eratosthenes used geometry to compute the earth’s circumference at 24,662 miles. The Hellenists are so accurate because they used the right measurements
