What is the angular diameter?

Because it doesn't make much sense to describe distant stars in units of length, we usually use the size we see on the earth to describe the size of celestial bodies, that is, the angle. Taking Sunday as 360 degrees, the size of the moon is about 0.5 degrees, that is, 30 minutes, 1800 seconds.
