![]() ![]() But this time, I am going to move back 160 meters so the total distance to the human is 200 meters. ![]() Next I will take another picture of the person and the moon. This would make an angular size of 0.044 radians or 2.5° (which is a larger angular size than the moon-just to be clear). Let's say this human is 1.75 meters tall and I am 40 meters away. The angular size of the person will depend on the distance to the person. The moon has an angular size of about a half a degree, so it's going to look rather small. Now let's take a picture of a person with the moon in the background. ![]() Here L is the length of the object and r is the distance from the object to the observer. ![]()
