Why visiting every planet is a logistical nightmare, not just a distance problem
In short: Traveling the solar system isn't as simple as pointing a rocket at a target. This video breaks down the complex orbital mechanics and environmental hazards that dictate how long it actually takes to reach our neighbors.
Interplanetary travel is governed by gravity wells, radiation, and propulsion limits rather than straight-line distance. For example, Mercury's intense gravity makes it more energy-consuming to reach than Mars. While Venus is closer to Earth, its extreme heat and pressure create significant mission risks.
The timeline scales dramatically with distance: a trip to Mars takes about 8 months, while round trips to Jupiter or Saturn can exceed a decade. Missions to the outer giants, Uranus and Neptune, could take over 20 years for a one-way journey alone.
