Your textbook wasn't wrong. It just used the sun as the reference frame. Switch to the galaxy, and the orbit you memorised in school becomes a helix. The sun moves through the Milky Way at 230 km/s. Planets spiral in its wake. Not circles — corkscrews through space. The helical model isn't a fringe idea. It's basic vector addition. #space #solarsystem #explained #science
