   Aug 6, 2020 · Voyager 2’s observations exposed its icy surface, at equilibrium with a tenuous atmosphere, measuring a pressure of just 14 micro-bar (McKinnon and Kirk, 2014, In: Encyclopedia of the Solar System, pp. 861-881). Images showed a variety of morphologies consistent with recent geological activity.

   Feb 27, 2023 · When Voyager 2 flew past Triton 143 years after its discovery, it revealed very few craters, indicating that Triton’s surface is relatively young: perhaps 50 million years old, or possibly even less than 10 million years old.

   Aug 25, 2009 · Triton was the last solid object visited by the Voyager 2 spacecraft on its epic 10-year tour of the outer solar system. Voyager mapped only the hemisphere that faces Neptune, but revealed a very young surface scarred by rising blobs of ice (diapirs), faults, and volcanic pits and lava flows composed of water and other ices.

   Aug 26, 2019 · On Aug. 25, passing about 3,408 miles above Neptune’s north pole, Voyager 2 made its closest approach to any planet since leaving Earth in 1977. This close encounter trajectory allowed Voyager 2 to pass about 25,000 miles from Triton about five hours later.

   Did Voyager 2 see Triton and Neptune?

   • A view of Triton and Neptune taken by Voyager 2. The Trident mission could have observed Triton both in sunlight and bathed in “Neptuneshine”. (credit: NASA/JPL-Caltech/Jason Major) Four hours and six seconds after they had been taken at Neptune, the images from Voyager 2 reached Earth in August 1989, and they showed something weird.

   Did Voyager 2 detect ice on Triton?

   • Before Voyager 2’s encounter with the Neptunian system, ground-based observations using infrared telescopes had detected CH 4 (methane) and N 2 (molecular nitrogen) ices on the surface of Triton (Cruikshank and Silvaggio, 1979, Astrophys J 233, 1016-1020; Cruikshank et al., 1984, Icarus 58, 293-305).

   What did Voyager discover about Triton?

   • Voyager also wowed scientists by revealing Triton’s surface to be very diverse, with several different types of terrain, most notably the “cantaloupe” terrain that covers much of its surface—named that because it looks like the skin of a cantaloupe.

   Will Voyager 2 reach Triton?

   • Together with its primary (Neptune), Triton is slowly traveling toward perihelion (its closest distance from the Sun), which it will reach on 3 September 2042. Therefore, when Voyager 2 approached Triton, it was farther from the Sun than it is now (Fig. 2), which would make it logical to expect warming.

   Did Voyager 2 have dark splotches?

   • Four hours and six seconds after they had been taken at Neptune, the images from Voyager 2 reached Earth in August 1989, and they showed something weird. Triton, a large moon that orbits Neptune backwards, opposite the direction that most of the other moons in the solar system do, had some dark splotches on its cold icy surface.

   Neptune's largest moon Triton, is seen in this mosaic of images captured by Voyager 2 during the only visit thus far to the Neptune system. Triton is one of only three objects in the Solar System known to have a nitrogen-dominated atmosphere (the others are Earth and Saturn's giant moon, Titan).
