How do you calculate diameter of moon? How was the diameter of the moon first calculated? An early Greek method was to measure the time that the Moon spends in a total eclipse and work out from that the size of...
How can we find the distance of the Moon by parallax method? How far away is the Moon? One way to find out is by using parallax: observe the Moon from two points on the Earth’s surface, and measure the shift...
What is the biggest contribution of Hipparchus? Hipparchus’s most important astronomical work concerned the orbits of the Sun and Moon, a determination of their sizes and distances from Earth, and the study of eclipses. When was Hipparchus known for? He is...
How was Aristarchus was able to measure the size of the Moon? Aristarchus realised that by investigating the motion of the Moon in the Earth’s shadow he could estimate its relative size. We do not know for certain how exactly he...
How did they measure the distance to the Moon? This distance is routinely measured using LIDAR (LIght Detection And Ranging) stations which bounce laser pulses off of the retroreflecting mirrors placed on the Moon by the Apollo astronauts. What tool helped...
How accurate is the distance to the Moon? From the ranging experiments, scientists know that the average distance between the centers of the Earth and the Moon is 385,000 kilometers with an accuracy of better than one part in 10 billion....
