Why Did Voyager 2 Visit the Gas Giants Before the Ice Giants?

💡 The Answer

• Voyager 2 was launched on a trajectory designed for gas giants Jupiter and Saturn.
• The gravity assists from these planets enabled later encounters with ice giants Uranus and Neptune.
• Without those initial flybys, reaching the ice giants would have been impossible with available technology.
• This sequence made Voyager 2 the first spacecraft to visit all four outer planets.
• The mission became a celebrated example of celestial mechanics and careful planning.
