Asteroseismology, a Common card
Asteroseismology is the study of oscillations in stars. Stars have many resonant modes and frequencies, and the path of sound waves passing through a star depends on the local speed of sound, which in turn depends on local temperature and chemical composition.

The facts on the card
The card carries these facts from its Wikipedia article.
- Because the resulting oscillation modes are sensitive to different parts of the star, they inform astronomers about the internal structure of the star, which is otherwise not directly possible from overall properties like brightness and surface temperature.
- Asteroseismology is closely related to helioseismology, the study of stellar pulsation specifically in the Sun.
- Though both are based on the same underlying physics, more and qualitatively different information is available for the Sun because its surface can be resolved.
Why it is Common
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Asteroseismology article was read about 11,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 63 and blocks with 41: each hit it takes is cut by 16 %.
How to get Asteroseismology
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.
