The facts on the card
The card carries these facts from its Wikipedia article.
- Classical Cepheids are also known as Population I Cepheids, Type I Cepheids, and Delta Cepheid variables.
- There exists a well-defined relationship between a classical Cepheid variable's luminosity and pulsation period, securing Cepheids as viable standard candles for establishing the galactic and extragalactic distance scales.
- Hubble Space Telescope observations of classical Cepheid variables have enabled firmer constraints on Hubble's law, which describes the expansion rate of the observable Universe.
Why it is Common
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Classical Cepheid variable article was read about 9,900 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 74 and blocks with 75: each hit it takes is cut by 30 %.
How to get Classical Cepheid variable
Open packs. Each pack holds five cards drawn from real Wikipedia articles, the rarest last, and the fifth card is always Rare or better. The odds are shown in the game. A free pack arrives every hour and two can wait, and the Coins you win in duels buy more packs.
