The facts on the card
The card carries these facts from its Wikipedia article.
- They have quasar-like nuclei with very high surface brightnesses whose spectra reveal strong, high-ionisation emission lines.
- However, unlike quasars, their host galaxies are clearly detectable.
- Seyfert galaxies account for about 10% of all galaxies and are some of the most intensely studied objects in astronomy, as they are thought to be powered by the same phenomena that occur in quasars, although they are closer and less luminous than quasars.
Why it is Uncommon
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Seyfert galaxy article was read about 55,000 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 85: each hit it takes is cut by 34 %.
