How to calculate angular size astronomy

Web11 apr. 2024 · If we know the angle the Sun takes up in the sky and how far away it is, we can calculate its true (linear) diameter, which is 1.39 million kilometers, or about 109 times the diameter of Earth. Unfortunately, the Sun is the only star whose angular diameter is easily measured. WebNow, calculate the angular diameter: degrees (For example, if your moon image was from the Main camera zoomed out, and it measures 350 pixels across, its angular diameter would be: 350 x .0014 = .49°) Now that you've measured the angular size of your image by either method, remember the equation from page 1: Distance to object = (size of object) …
