Lagrange point, a Rare card
In celestial mechanics, the Lagrange points, also called the Lagrangian points or libration points, are points of equilibrium for small-mass objects under the gravitational influence of two massive orbiting bodies.

Lagrange point quiz: 3 questions
Three questions on the Lagrange point card, the way WikiCards duels ask them. Pick an answer, the facts are just below.
Find the missing word
Mathematically, this involves the solution of the ______ three-body problem.
Answer
restricted. Mathematically, this involves the solution of the restricted three-body problem. From the Lagrange point article on Wikipedia.
Which of these cards hits hardest (highest ATK)?
Answer
Compressed-air energy storage. Compressed-air energy storage 81 · Lagrange point 77 · Ali Baba and the Forty Thieves 74 · Cecil Wood 71 ATK in WikiCards.
Which of these Wikipedia articles is read the most in a year?
Answer
Lagrange point. Lagrange point 380,000 · Compressed-air energy storage 26,000 · 1953 in spaceflight 2,100 · Cecil Wood 1,100 Wikipedia reads over a year.
In a duel, each round asks a question like these about the opposing card, with 15 seconds to answer.
The facts on the card
The card carries these facts from its Wikipedia article.
- Mathematically, this involves the solution of the restricted three-body problem.
- Normally, the two massive bodies exert an unbalanced gravitational force at a point, altering the orbit of any other celestial body at that point.
- At the Lagrange points, the gravitational forces of the two large bodies and the centrifugal pseudo-force balance each other.
Why it is Rare
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Lagrange point article was read about 380,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 77 and blocks with 75: each hit it takes is cut by 30 %.
How to get Lagrange point
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.
