The facts on the card
The card carries these facts from its Wikipedia article.
- It is involved in the calculation of gravitational effects in Isaac Newton's law of universal gravitation and in Albert Einstein's theory of general relativity.
- It is also known as the universal gravitational constant, the Newtonian constant of gravitation, or the Cavendish gravitational constant, denoted by the capital letter G. It is contrastable with the Einstein gravitational constant, denoted by lowercase kappa.
- In Newton's law, it is the proportionality constant connecting the gravitational force between two bodies with the product of their masses and the inverse square of their distance.
Why it is Rare
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Gravitational constant article was read about 290,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 76 and blocks with 68: each hit it takes is cut by 27 %.
How to get Gravitational constant
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.
