Planetary attribution
The tarot cards of Uranus
Disruption, sudden freedom and the step off the edge.
Uranus takes The Fool, and takes nothing else. That is not an oversight: Uranus, Neptune and Pluto were discovered long after the pip attributions were fixed, so the modern planets were fitted to single trumps rather than woven through the deck.
The pairing is apt. Uranus is the break in the pattern, and The Fool is the card outside the sequence, unnumbered in the oldest decks and playable at any point.
1 card
A single trump. The modern planets were fitted to the deck long after the numbered cards were attributed, so they take one card each and no pips.
The other planets
Where these attributions come from
The Hermetic Order of the Golden Dawn, in the late nineteenth century. They mapped the whole deck onto the zodiac, the planets and the Hebrew alphabet, and the Rider-Waite-Smith deck was built on that system, which is why most modern decks still inherit it.
It is a system rather than a discovery. The fifteenth century Italian decks had no astrological scheme at all, and other traditions map the cards differently. Every attribution on this site is the Golden Dawn one, and where a card is disputed its own page says so.
