The big gap in Saturn's rings is caused by a moon much further out that has an orbital period double that of the gap! We've even found exoplanet systems with these patterns. They're all the result of orbital resonance. This video explains how that mechanism works. CORRECTION: In the video I say that Ganymede, Europa and Io are the largest moons are jupiter. Actually here are the 4 largest moons from largest to smallest: Ganymede Callisto Io Europa Here's my video on resonance: youtu.be/dihQuwrf9yQ Here's my video about bad maths: youtu.be/C91gKuxutTU This is Dr Becky Smethurst's channel: youtube.com/channel/UCYNbYGl89UUowy8oXkipC-Q This is Beardyman's channel: youtube.com/user/beardyman This is Jay Foreman's channel: youtube.com/user/jayforeman51 This is the Veritasium video mentioned at the start: youtu.be/t-_VPRCtiUg Here's the paper I found that explains orbital resonance: articles.adsabs.harvard.edu/pdf/1976ARA%26A..14..215P Image credits: Picture of Dwayne Johnson - Aarón Sánchez You can buy my books here: stevemould.com/books You can support me on Patreon here: patreon.com/stevemould just like these amazing people: GMatthew Cocke Glenn Watson Joseph Rocca Joël van der Loo Doug Peterson Rashid Al M Paul Warelis Will Ackerly Heather Liu Alnitak Twitter: twitter.com/moulds Instagram: instagram.com/stevemouldscience Facebook: facebook.com/stevemouldscience Buy nerdy maths things: mathsgear.co.uk
