Plot 1 is viewed from the north ecliptic pole, to scale. Plots 2 to 4 are third-angle projections at 20% scale. In the SVG file, hover over a trajectory or orbit to highlight it and its associated launches and flybys. Voyager 2 is a space probe launched by NASA on August 20, 1977, as a part of the Voyager program.
Voyager 2 is the only spacecraft to study all four of the solar system's giant planets at close range. Voyager 2 discovered a 14th moon at Jupiter. Voyager 2 was the first human-made object to fly past Uranus. At Uranus, Voyager 2 discovered 10 new moons and two new rings. Voyager 2 was the first human-made object to fly by Neptune.

- How Triton Got Its Name
Triton was discovered on Oct. 10, 1846 by British astronomer William Lassell, just 17 days after Neptune itself was discovered.
Triton is the largest of Neptune's 13 moons. It is unusual because it is the only large moon in our solar system that orbits in the opposite direction of its planet's rotation―a retrograde orbit. Scientists think Triton is a Kuiper Belt Object captured by Neptune's gravity millions of years ago. It shares many similarities with Pluto, the best know...
Triton is named after the son of Poseidon (the Greek god comparable to the Roman Neptune). Until the discovery of the second moon Nereid in 1949, Triton was commonly known as simply "the satellite of Neptune."
When Voyager flew within 5,000 kilometers (3,000 miles) of Neptune on August 25, 1989, the planet was the most distant member of the solar system from the Sun. (Pluto once again will become most distant in 1999.) Neptune orbits the Sun every 165 years. It is the smallest of our solar system's gas giants.
Aug 22, 2019 · Credits: NASA/JPL-Caltech. Thirty years ago, on Aug. 25, 1989, NASA’s Voyager 2 spacecraft made a close flyby of Neptune, giving humanity its first close-up of our solar system’s eighth planet. Marking the end of the Voyager mission’s Grand Tour of the solar system’s four giant planets — Jupiter, Saturn, Uranus and Neptune — that ...
Aug 21, 2014 · The new Triton map has a resolution of 1,970 feet (600 meters) per pixel. The colors have been enhanced to bring out contrast but are a close approximation to Triton's natural colors. Voyager's "eyes" saw in colors slightly different from human eyes, and this map was produced using orange, green and blue filter images.

Voyager 2 's observation phase proper of Neptune began 5 June 1989, the spacecraft officially reached the Neptunian system on 25 August, and data collection ceased on 2 October. [4] Initially it was planned to use a trajectory that resulted in Voyager 2 passing around 1,300 km (810 mi) from Neptune and 8,200 km (5,100 mi) from Triton. [ 5 ]
