The facts on the card
The card carries these facts from its Wikipedia article.
- During the twilight period, the shadow's visible fringe , sometimes called the dark segment or twilight wedge, appears as a dark and diffuse band just above the horizon, most distinct when the sky is clear.
- Since the angular diameters of the Sun and the Moon as viewed from Earth's surface are almost the same, the ratio of the length of Earth's shadow to the distance between Earth and the Moon will be almost equal to the ratio of the diameters of Earth and the Moon.
- Since Earth's diameter is 3.7 times the Moon's, the length of the planet's umbra is correspondingly 3.7 times the average distance from the Moon to Earth: about 1.4 million km.
Why it is Uncommon
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Earth's shadow article was read about 27,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 52 and blocks with 38: each hit it takes is cut by 15 %.
