☾ The sky
Real stars from the catalogue, the constellation figures and the road of the zodiac - with the seven lights where they actually stand tonight. Drag to turn the sky; the wheel brings it closer.

The sky in real time: real catalogue stars, the constellations, and where the planets are right now. It is an astronomical picture rather than an astrological diagram - what is actually overhead if you go out and look the right way.
Find a planet in the list and see which sign it is in and how high it stands. The planets keep to a narrow band - the ecliptic - so they always lie along roughly one arc; find one and the rest are near it. The Moon moves fastest and changes sign about every two and a half days.
Directly, nothing, and that is the honest answer. But the majors have long been associated with planets and signs, the correspondences are listed on the card pages, and seeing Saturn as a real object rather than a symbol in a table changes that association slightly. A birth chart is built from these same positions, taken on the date you were born.
