The facts on the card
The card carries these facts from its Wikipedia article.
- It is often colloquially known as the Hubble tuning-fork diagram because the shape in which it is traditionally represented resembles a tuning fork.
- It was invented by John Henry Reynolds and Sir James Jeans.
- The tuning fork scheme divided regular galaxies into three broad classes – ellipticals, lenticulars and spirals – based on their visual appearance.
Why it is Uncommon
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Hubble sequence article was read about 20,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 67 and blocks with 56: each hit it takes is cut by 22 %.
