When humanity first dreamed of traveling to other worlds, the distances seemed insurmountable. But how long does it actually take to reach each planet—not in a straight line, but according to the laws of orbital mechanics?
In this video, we explore what determines the duration of interplanetary flights: Hohmann trajectories, launch windows, gravity assists, fuel limitations (the Tsiolkovsky equation), and real-world mission examples.
You'll learn why Venus takes months, Mars six months, Jupiter and Saturn years, and Mercury can take 6-7 years, even though it's "closer."
