How Long Would It Take Us To Go To Neptune?

Have we only gone once?
Although it sounds hard to believe, the ice giant Neptune has only been visited by a single spacecraft in all of human history, and that spacecraft was the Voyager 2 probe, which passed close to Neptune's orbit in 1989.
The Voyager 2 probe was part of the Voyager mission, which consisted of two space exploration probes, Voyager 1 and Voyager 2, whose main objective was to study the outer planets, about which, until then, very little was known.

The only way to travel without fuel
Gravity assist is a space maneuver in which a ship uses a planet's gravity to change its speed and direction. Used in missions such as Voyager, it saves fuel and accelerates spaceships to speeds that they would never reach with conventional fuel to reach their objectives in less time.

Voyager 2 Voyage
Voyager 2 was launched in 1977 and undertook an epic journey through the outer solar system. It used gravity assistance from Jupiter and Saturn during its journey to head towards more distant planets. In August 1989, after more than a decade of journey, Voyager 2 approached Neptune, becoming the first and only spacecraft to explore this planet up close.

Orbital Velocity
To better explain this, imagine a car race; in car races, all the cars go at extremely high speeds, and although each car moves at a different speed, they all go so fast that if one of the drivers were to brake suddenly, At the moment of pressing the brake pedal, it would not stay in the place where it braked, but would advance several tens of meters until it braked completely.
