How long would it take to get to Saturn?
151 yearsby jet, without stopping
Saturn comes within 1,195 million km of Earth at closest approach. In a straight line at airliner speed that's 151 years of continuous flight. The fastest spacecraft ever launched would need 2.3 years.

The honest timetable
Family car (100 km/h)
1,363 years
Jet airliner (900 km/h)
151 years
New Horizons — fastest launch ever (58,500 km/h)
2.3 years
Light (299,792 km/s)
1.1 hours
Those are straight-line times at the moment of closest approach — the absolute best case. Real spacecraft can't fly straight there: they follow long curved transfer orbits, sling around planets for free speed, and have to slow down at the other end. Cassini took 6 years and 9 months to reach Saturn (1997–2004), using flybys of Venus (twice), Earth and Jupiter to build up speed.
Saturn’s mean density is less than water — it would float. The rings may be younger than the dinosaurs, and are as little as 10 m thick.
