I assume you mean launched to Neptune, and not in Neptune. Only one spacecraft has ever visited Neptune, and that is Voyager 2 which passed by there in 1989.
The name of the space probe that visited outer planets is Voyager. Voyager 1 and Voyager 2 were launched by NASA in 1977 to explore the outer planets of our solar system, including Jupiter, Saturn, Uranus, and Neptune.
The Soviet Union was the first country to launch a space probe. The first successful spacecraft to reach the Moon was Luna 2 in 1959.
Voyager 2 is a space probe launched by NASA in 1977. It has explored the outer planets of our solar system, including Jupiter, Saturn, Uranus, and Neptune, providing valuable data and images of these distant worlds. Voyager 2 is currently the only spacecraft to have visited Uranus and Neptune.
The space probe launched in October 1997 was the Cassini-Huygens mission. It was a joint project between NASA, the European Space Agency, and the Italian Space Agency, and its primary mission was to study Saturn and its moons.
The first U.S. space probe was named Explorer 1. It was launched on January 31, 1958, and discovered the Van Allen radiation belt.
the second space probe launched was called the kooterliker01
the year that the ranger space probe was launched was in 1964.
Viking 1 was actually a Martian space probe launched in 1975 by NASA. It was the first successful probe to land on Mars. It was launched by a Titan rocket with a Centaur upper stage.
The first space probe was the satellite Sputnik I launched in 1957.
The last space probe launched was the Tianwen-1 mission to Mars, which launched in July 2020 by the China National Space Administration.
Neptune was last visited by the Voyager 2 spacecraft in 1989. Voyager 2 made a flyby of the planet to study its atmosphere, moons, and rings before continuing on its journey out of the solar system.
The name of the space probe that visited outer planets is Voyager. Voyager 1 and Voyager 2 were launched by NASA in 1977 to explore the outer planets of our solar system, including Jupiter, Saturn, Uranus, and Neptune.
The first successful Mars probe, Mars 1, was launched from the USSR on November 1, 1962. The most recent probe, India's Mangalyaan (Mars Orbiter Mission), was launched on November 5, 2013, and reached Martian orbit on September 24, 2014.

This might not be completely accurate but I'm positive this is the general idea. A space probe is launched from a rocket. When the rocket reaches a certain distance into space, parts of the rocket that aren't necessary to carry the probe to its destination break loose from the rocket.
The Russians invented the space probe and launched it into space on october 4, 1957.
