How to Calculate the Angular Diameter of the Sun Sciencing
Using the Sun ————-There are two useful things about the Sun. First it is something with a known angular size. Second, the motion in the sky has a known angular speed (about 2 π radians... An example of that is that even though the Sun and the Moon have the same angular size, the Sun is in fact much larger than the Moon. They just appear the same size because the Sun is much farther. So from accurate measurements of the distance to the Sun and to the Moon, and measuring their angular sizes, we can get good estimates of their actual sizes. The values we get are that the radius of
What is Angular Size? Perfect Astronomy
This same concept of angles and degrees is used to measure the angular diameter or angular (apparent) size of a celestial object. The angular diameter is the angle that's made by two lines... Since it is easy to measure the angular size of astronomical objects, we often use this to solve for other unknowns, such as the distance or the diameter of a celestial body. If two objects are roughly the same distance from the observer, you can also use the formula to find the distance between the two objects.
Angular Size Physics Forums
you end up with an object with an angular diameter that is 10 times bigger than this, you can easily imagine how big it would look in the sky (i.e. 10 times the size of the sun or full moon). And as a further example, let's look at Jupiter's largest satellite, Ganymede.... Examples from astronomy: the moon has a size of approximately 3500 km (g) and a distance of 400000 km (r). It has an apparent size of about 0.5 degrees (α). The galaxy M51 is about 31 megalight-years away from us and has an angular diameter of 0.19 degrees, which corresponds to …

I had found a formula a few months back that was very simple because the formula was modified due to the angles being so small....

- Angular Size. Angular size is a Greek geometric concept for astronomical measurement and it is also the basis for modern astronomy. The angular size can be measured in units of radians, units of degrees, arc minutes (1degree= 60 arc minutes) and arc seconds (one second= 60 arc seconds).
