The facts on the card
The card carries these facts from its Wikipedia article.
- It contains the nearest stars and brown dwarfs and, among others, the Local Interstellar Cloud, the neighboring G-Cloud, the Ursa Major moving group, and the Hyades.
- It is estimated to be at least 1000 light years in size, and is defined by its neutral-hydrogen density of about 0.05 atoms/cm3, or approximately one tenth of the average for the ISM in the Milky Way, and one sixth that of the Local Interstellar Cloud.
- The exceptionally sparse gas of the Local Bubble is the result of supernovae that exploded within the past ten to twenty million years.
Why it is Uncommon
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Local Bubble article was read about 59,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 65 and blocks with 53: each hit it takes is cut by 21 %.
