What Is The Sun'S Approximate Physical Diameter?

What distance is represented by each degree of latitude?? What distance is represented by each arcminute of latitude?? Can you give similar answers for the distances represented by a degree or arc minute of longitude? Why or why not? Version 7 Find the Sun's Diameter. The Sun has an angular diameter of about 0.5 _ and an average distance from Earth of about 150 million km. What is the Sun's approximate physical diameter? Compare your answer to the actual value of 1,390,000 km.

Circumference = 2¹r = 2¹ (6371 km) = 40000 km equator to pole distance = Circumference 4 =40000 km, 4 = 10000 km, Thus, 1_ = 10000 km 90_ = 111 km Each arcminute of latitude represents 1.85 kilometers. We cannot provide similar answers for longitude, because lines of longitude get closer together as we near the poles, eventually meeting at the poles themselves. So there is no single distance that can represent 1_ of longitude everywhere on Earth. - Physical size = 2¹ _ distance _ angular size/360 degrees - Sun is 0.5 degrees in angular diameter Å 1.5 _ 10^8 - Physical size = 2¹ x (1.5 x 10^8 km) x (0.5 degrees)/360 degrees = 1.31 x 10^6 km
