Web16 de fev. de 2024 · We have investigated the practicability of Aristarchus' method of determining the Sun's and the Moon's sizes and distances from Earth using a simple 8-in. telescope and a digital camera. WebAristarchus estimated 3.3d distance to the Sun using a measurement of the angle between Moon and Sun at half Moon - this came to between 18 to 20 times the distance to the Moon, a serious underestimate as it turned out. He realised that the angular size of the Moon and the Sun in the sky were roughly the same i.e. the Moon’s great ink font
Solved ACTIVITY 7 Aristarchus Measures the size and Distance
WebAristarchus determined the size of the Moon by comparing the time it took to travel through Earth's shadow with the time it took to move a distance equal to its diameter. By timing how long a bright star was obscured by the Moon, he was able to compare these two times and deduce that the shadow was about 8/3 the diameter of the Moon.
