The facts on the card
The card carries these facts from its Wikipedia article.
- In the vision sciences, it is called the visual angle, and in optics, it is the angular aperture.
- The angular diameter can alternatively be thought of as the angular displacement through which an eye or camera must rotate to look from one side of an apparent circle to the opposite side.
- A person can resolve with their naked eyes diameters down to about 1 arcminute.
Why it is Uncommon
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Angular diameter article was read about 43,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 68 and blocks with 55: each hit it takes is cut by 22 %.
