“He found the Moon’s diameter to be between 0.32 and 0.40 times the diameter of Earth and the Sun’s diameter to be between 6.3 and 7.2 times the diameter of Earth.”

How did Aristarchus measure the angle between the Moon and the Sun?

“Aristarchus began with the premise that, during a half moon, the moon forms a right triangle with the Sun and Earth. By observing the angle between the Sun and Moon, φ, the ratio of the distances to the Sun and Moon could be deduced using a form of trigonometry.”

How did Aristarchus calculate the distance to the Moon?

“Aristarchus timed how long the Moon took to travel through Earth’s shadow and compared this with the time required for the Moon to move a distance equal to its diameter (this could be done by timing how long a bright star in obscured by the Moon).”

When was the Sun first discovered?

“It’s kind of impossible to say when the Sun was discovered, since the first life forms on Earth probably relied on its energy. Humans have been well aware of the Sun for tens of thousands of years, and before modern astronomy had no idea what it was.”

What was Aristarchus most famous discovery?

How did the Greeks know the Sun was far away?

“Aristarchus concluded that the Sun was much further away than the Moon (by about a factor 20), by claiming that the angle between the Earth, Moon and Sun, when the Moon was half-illuminated, was 87 degrees.”

Why did Aristarchus make his measurements of the Sun’s distance at the time of a half moon?

“Answer and Explanation: Aristarchus made his measurement between the Earth-Sun distance and Earth-Moon distance during a half Moon because the points representing the Earth, Moon and the Sun form a right triangle.”

Who came first Aristarchus and Copernicus?

“George Sarton, the distinguished professor at Harvard University, has written in his monumental “A History of Science”: “Aristarchos had conceived what we call the Copernican universe, eighteen centuries before Copernicus.”

Who named sun first?

“Answer and Explanation: No one person is credited with naming the sun; this occurred as the result of language transmission throughout many centuries. In ancient Rome, the sun was known as ‘Sol’, and later, as the Romance languages began taking shape, it took on several minor variations such as ‘sonne’.”
