Another example:
If you step outside and gaze at the Southern Cross (Crux), have a look at the “bottom” star, Acrux and the top star, “Gacrux” which define the long axis of Crux.
The angular distance between these 2 stars is approx 6 degrees. So, you could fit 12 full Moons in between these 2 stars. (12 x ½ degree = 6 degrees).
Generally, this is how amateur astronomers measure distances between objects, using degrees, arc minutes and arc seconds.
Here are some examples:
Full Moon is approx 30 arc mins in diameter.
Sun is approx 30 arc mins in diameter.
Jupiter ranges from 30 arc secs to around 45 arc secs in diameter.
