The Lighthouse of Alexandria is expounded to were greater than one hundred ten meters (361 feet) excessive. yet Alexandria used to be no longer the single harbor to boast one of many wonders of the area. within the historic Greek urban of Rhodes, beside Mandrákion harbor, there stood a massive statue of the solar god Helios. The statue, the Colossus of Rhodes, used to be acknowledged to be 70 cubits excessive (about 32 meters/105 ft). The Brightness of the celebs within the moment century BC, whilst the astronomer Hipparchus (190–120 BC) labored in Rhodes, the Colossus used to be nonetheless remembered through the aged citizens of the town. at present Alexandria remained unchallenged within the historic international because the maximum heart of studying. even though, in Hipparchus, Rhodes had an astronomer moment to none on the time. Hipparchus made precious contributions to trigonometry. He had a valid knowing of the geometry of the field, and he was once the 1st to indicate mesh of imaginary circles that we now name range and longitude have been the precise coordinates for mapping the outside of the Earth. utilizing a similar procedure he labored out a round coordinate procedure for the heavens similar to that used for the Earth. Hipparchus’ maximum success, in spite of the fact that, was once that via learning the heavens he outfitted up a catalog of the celebrities and adequately recorded the positions of 850 of them within the evening sky. it's a degree of his looking at ability that he additionally assigned a level of brightness to each superstar on a scale of 1 to 6. lower than his method significance one denoted the brightest stars and importance six indicated the faintest stars.

Like Aristarchus (c. 310–230 BC) and others sooner than him Hipparchus desired to degree the size of the sun system—the distances from the Earth to the Moon and from the Earth to the solar. If he may well locate those distances then he might simply calculate the dimensions of the sunlight and the Moon from their angular diameter of part a level or half-hour of arc. He was once capable of calculate the space to the Moon with out even leaving the island of Rhodes. He knew from the astronomical files new release ahead of his time a complete eclipse of the solar were saw and recorded on the Hellespont, close to the town of Byzantium. He stumbled on that this similar eclipse had additionally been saw at Alexandria, yet as the latter used to be 500 miles (805 km) to the south, the eclipse used to be no longer overall in Egypt.
